Extrapyramidal side-effects (EPSE’s) are a group of side effects that affect voluntary motor control, commonly seen in patients taking antipsychotic drugs. EPSE’s include dystonias, parkinsonism, akathisia, and tardive dyskinesia. They can be frightening and uncomfortable, leading to problems with non-compliance and can even be life-threatening in the case of laryngeal dystonia. EPSE’s are thought to be due to antagonism of dopaminergic D2 receptors in the basal ganglia. Symptoms generally occur within the first few days of treatment, with dystonias appearing quickly, within a few hours of administration of the first dose. Newer antipsychotics tend to produce less EPSE’s, with clozapine carrying the lowest risk and haloperidol carrying the highest risk. Akathisia is the most resistant EPSE to treat. EPSE’s can also occur when antipsychotics are discontinued (withdrawal dystonia).

The trigeminal nerve, which is the largest cranial nerve, serves both sensory and motor functions. It is composed of three primary branches, namely the ophthalmic, maxillary, and mandibular branches. This nerve is responsible for providing sensory information to the face and head, while also controlling the muscles involved in chewing. On the other hand, the facial nerve is responsible for controlling the muscles that enable facial expressions and transmitting information from the front two-thirds of the tongue.

Overview of Cranial Nerves and Their Functions

The cranial nerves are a complex system of nerves that originate from the brain and control various functions of the head and neck. There are twelve cranial nerves, each with a specific function and origin. The following table provides a simplified overview of the cranial nerves, including their origin, skull exit, modality, and functions.

The first cranial nerve, the olfactory nerve, originates from the telencephalon and exits through the cribriform plate. It is a sensory nerve that controls the sense of smell. The second cranial nerve, the optic nerve, originates from the diencephalon and exits through the optic foramen. It is a sensory nerve that controls vision.

The third cranial nerve, the oculomotor nerve, originates from the midbrain and exits through the superior orbital fissure. It is a motor nerve that controls eye movement, pupillary constriction, and lens accommodation. The fourth cranial nerve, the trochlear nerve, also originates from the midbrain and exits through the superior orbital fissure. It is a motor nerve that controls eye movement.

The fifth cranial nerve, the trigeminal nerve, originates from the pons and exits through different foramina depending on the division. It is a mixed nerve that controls chewing and sensation of the anterior 2/3 of the scalp. It also tenses the tympanic membrane to dampen loud noises.

The sixth cranial nerve, the abducens nerve, originates from the pons and exits through the superior orbital fissure. It is a motor nerve that controls eye movement. The seventh cranial nerve, the facial nerve, also originates from the pons and exits through the internal auditory canal. It is a mixed nerve that controls facial expression, taste of the anterior 2/3 of the tongue, and tension on the stapes to dampen loud noises.

The eighth cranial nerve, the vestibulocochlear nerve, originates from the pons and exits through the internal auditory canal. It is a sensory nerve that controls hearing. The ninth cranial nerve, the glossopharyngeal nerve, originates from the medulla and exits through the jugular foramen. It is a mixed nerve that controls taste of the posterior 1/3 of the tongue, elevation of the larynx and pharynx, and swallowing.

The tenth cranial nerve, the vagus nerve, also originates from the medulla and exits through the jugular foramen. It is a mixed nerve that controls swallowing, voice production, and parasympathetic supply to nearly all thoracic and abdominal viscera. The eleventh cranial nerve, the accessory nerve, originates from the medulla and exits through the jugular foramen. It is a motor nerve that controls shoulder shrugging and head turning.

The twelfth cranial nerve, the hypoglossal nerve, originates from the medulla and exits through the hypoglossal canal. It is a motor nerve that controls tongue movement. Overall, the cranial nerves play a crucial role in controlling various functions of the head and neck, and any damage of dysfunction can have significant consequences.

Benzodiazepines are a class of drugs commonly used to treat anxiety and sleep disorders. It is important to have a working knowledge of the more common benzodiazepines and their half-life. Half-life refers to the amount of time it takes for half of the drug to be eliminated from the body.

Some of the more common benzodiazepines and their half-life include diazepam with a half-life of 20-100 hours, clonazepam with a half-life of 18-50 hours, chlordiazepoxide with a half-life of 5-30 hours, nitrazepam with a half-life of 15-38 hours, temazepam with a half-life of 8-22 hours, lorazepam with a half-life of 10-20 hours, alprazolam with a half-life of 10-15 hours, oxazepam with a half-life of 6-10 hours, zopiclone with a half-life of 5-6 hours, zolpidem with a half-life of 2 hours, and zaleplon with a half-life of 2 hours. Understanding the half-life of these drugs is important for determining dosages and timing of administration.

The mother seems to transfer her own feelings of insecurity onto her daughter, who internalizes them even though she has a healthy weight. This phenomenon is known as projective identification, where the projected emotions are adopted and experienced as one’s own.

Intermediate Mechanism: Rationalisation

Rationalisation is a defense mechanism commonly used by individuals to create false but credible justifications for their behavior of actions. It involves the use of logical reasoning to explain away of justify unacceptable behavior of feelings. The individual may not be aware that they are using this mechanism, and it can be difficult to identify in oneself.

Rationalisation is considered an intermediate mechanism, as it is common in healthy individuals from ages three to ninety, as well as in neurotic disorders and in mastering acute adult stress. It can be dramatically changed by conventional psychotherapeutic interpretation.

Examples of rationalisation include a student who fails an exam and blames the teacher for not teaching the material well enough, of a person who cheats on their partner and justifies it by saying their partner was neglectful of unaffectionate. It allows the individual to avoid taking responsibility for their actions and to maintain a positive self-image.

Overall, rationalisation can be a useful defense mechanism in certain situations, but it can also be harmful if it leads to a lack of accountability and an inability to learn from mistakes.

The Declaration of Helsinki is a set of ethical principles for human experimentation and research, established by the World Medical Association. It is their most well-known policy statement and has been amended six times since its adoption in 1964. The most recent version was adopted at the 64th General Assembly in Fortaleza, Brazil, in October 2013 and is the only official version. Previous versions should not be used of referenced, except for historical purposes.

The typical EEG pattern for CJD includes periodic sharp wave complexes, which is a diagnostic criterion. Lewy body dementia may show generalized slow wave activity, but if it is more prominent in the temporal and parietal regions, it may indicate Alzheimer’s disease. Toxic encephalopathies, such as lithium toxicity, may show periodic triphasic waves on EEG. For more information, see Smith SJ’s article EEG in neurological conditions other than epilepsy: when does it help, what does it add? (2005).

The Bazett formula adjusts the QT interval for heart rate by taking the square root of the R-R interval and dividing the QT interval by it.

QTc Prolongation: Risks and Identification

The QT interval is a measure of the time it takes for the ventricles to repolarize and is calculated from the beginning of the QRS complex to the end of the T wave. However, the QT interval varies with the heart rate, making it difficult to use a single number as a cut-off for a prolonged QT. Instead, a corrected QT interval (QTc) is calculated for each heart rate using various formulas. A QTc over the 99th percentile is considered abnormally prolonged, with approximate values of 470 ms for males and 480 ms for females.

Prolonged QT intervals can lead to torsade de pointes (TdP), a polymorphic ventricular tachycardia that can be fatal if it degenerates into ventricular fibrillation. TdP is characterized by a twisting of the QRS complexes around an isoelectric line and is often asymptomatic but can also be associated with syncope and death. An accurate diagnosis requires an ECG to be recorded during the event. It is important to note that an increase in the QT interval due to a new conduction block should not be considered indicative of acquired LQTS and risk for TdP.

The hormone ADH (also known as vasopressin) is released from the posterior pituitary gland and promotes water retention and increased blood pressure by constricting arterioles. Conversely, the hormones ACTH, growth hormone, luteinizing hormone, and thyroid stimulating hormone are all released from the anterior pituitary gland and have various effects on the body, such as stimulating hormone production in the adrenal glands, promoting bone and muscle growth, regulating sex gland function, and stimulating the release of thyroxine.

Nitrous oxide functions as a vasodilator during penile erection by diffusing through the muscle cell membrane and binding to guanylyl cyclase. This enzyme catalyzes the conversion of GTP to cyclic GMP, which activates a cGMP-dependent protein kinase. This kinase stimulates the uptake of calcium by the endoplasmic reticulum of the muscle cell, leading to muscle relaxation and vasodilation, resulting in an erection.

To end the erection, cGMP is converted into GMP by a specific phosphodiesterase (PDE). There are ten families of PDEs, with PDE5 being the primary PDE found in vascular smooth muscle. Sildenafil (Viagra) is a specific inhibitor of PDE5, blocking the breakdown of cGMP and prolonging the effects of cGMP, thereby prolonging the erection.

Mechanisms of Action of Different Drugs

Understanding the mechanisms of action of different drugs is crucial for medical professionals. It is a common topic in exams and can earn easy marks if studied well. This article provides a list of drugs and their mechanisms of action in different categories such as antidepressants, anti dementia drugs, mood stabilizers, anxiolytic/hypnotic drugs, antipsychotics, drugs of abuse, and other drugs. For example, mirtazapine is a noradrenaline and serotonin specific antidepressant that works as a 5HT2 antagonist, 5HT3 antagonist, H1 antagonist, alpha 1 and alpha 2 antagonist, and moderate muscarinic antagonist. Similarly, donepezil is a reversible acetylcholinesterase inhibitor used as an anti dementia drug, while valproate is a GABA agonist and NMDA antagonist used as a mood stabilizer. The article also explains the mechanisms of action of drugs such as ketamine, phencyclidine, buprenorphine, naloxone, atomoxetine, varenicline, disulfiram, acamprosate, and sildenafil.

Electroencephalography

Electroencephalography (EEG) is a clinical test that records the brain’s spontaneous electrical activity over a short period of time using multiple electrodes placed on the scalp. It is mainly used to rule out organic conditions and can help differentiate dementia from other disorders such as metabolic encephalopathies, CJD, herpes encephalitis, and non-convulsive status epilepticus. EEG can also distinguish possible psychotic episodes and acute confusional states from non-convulsive status epilepticus.

Not all abnormal EEGs represent an underlying condition, and psychotropic medications can affect EEG findings. EEG abnormalities can also be triggered purposely by activation procedures such as hyperventilation, photic stimulation, certain drugs, and sleep deprivation.

Specific waveforms are seen in an EEG, including delta, theta, alpha, sigma, beta, and gamma waves. Delta waves are found frontally in adults and posteriorly in children during slow wave sleep, and excessive amounts when awake may indicate pathology. Theta waves are generally seen in young children, drowsy and sleeping adults, and during meditation. Alpha waves are seen posteriorly when relaxed and when the eyes are closed, and are also seen in meditation. Sigma waves are bursts of oscillatory activity that occur in stage 2 sleep. Beta waves are seen frontally when busy of concentrating, and gamma waves are seen in advanced/very experienced meditators.

Certain conditions are associated with specific EEG changes, such as nonspecific slowing in early CJD, low voltage EEG in Huntington’s, diffuse slowing in encephalopathy, and reduced alpha and beta with increased delta and theta in Alzheimer’s.

Common epileptiform patterns include spikes, spike/sharp waves, and spike-waves. Medications can have important effects on EEG findings, with clozapine decreasing alpha and increasing delta and theta, lithium increasing all waveforms, lamotrigine decreasing all waveforms, and valproate having inconclusive effects on delta and theta and increasing beta.

Overall, EEG is a useful tool in clinical contexts for ruling out organic conditions and differentiating between various disorders.

Tricyclic antidepressants are known to cause various side effects, which can be attributed to their mechanisms of action. These include antimuscarinic effects, which can lead to dry mouth and urinary retention, antihistaminergic effects, which can cause weight gain and drowsiness, antiadrenergic effects, which can result in postural hypotension, sexual dysfunction, and cognitive impairment, and antiserotonergic effects, which can lead to weight gain. Additionally, tricyclic antidepressants can cause cardiotoxicity and reduce the seizure threshold due to their membrane stabilizing effects. Other important side effects of these drugs include arrhythmias and ECG changes, black tongue, tremor, altered liver function tests, paralytic ileus, and neuroleptic malignant syndrome. Black hairy tongue, a harmless condition where the tongue appears black and hairy due to elongated filiform papillae, is also a possible side effect of tricyclic antidepressants.

In psychiatry, various questionnaires and interviews are used to assess different conditions and areas. It is important for candidates to know whether certain assessment tools are self-rated of require clinical assistance. The table provided by the college lists some of the commonly used assessment tools and indicates whether they are self-rated of clinician-rated. For example, the HAMD and MADRS are clinician-rated scales used to assess the severity of depression, while the GDS is a self-rated scale used to screen for depression in the elderly. The YMRS is a clinician-rated scale used to assess the severity of mania in patients with bipolar disorder, while the Y-BOCS is used to measure both the severity of OCD and the response to treatment. The GAF provides a single measure of global functioning, while the CGI requires the clinician to rate the severity of the patient’s illness at the time of assessment. The CAMDEX is a tool developed to assist in the early diagnosis and measurement of dementia in the elderly.

Genomics: Understanding DNA, RNA, Transcription, and Translation

Deoxyribonucleic acid (DNA) is a molecule composed of two chains that coil around each other to form a double helix. DNA is organised into chromosomes, and each chromosome is made up of DNA coiled around proteins called histones. RNA, on the other hand, is made from a long chain of nucleotide units and is usually single-stranded. RNA is transcribed from DNA by enzymes called RNA polymerases and is central to protein synthesis.

Transcription is the synthesis of RNA from a DNA template, and it consists of three main steps: initiation, elongation, and termination. RNA polymerase binds at a sequence of DNA called the promoter, and the transcriptome is the collection of RNA molecules that results from transcription. Translation, on the other hand, refers to the synthesis of polypeptides (proteins) from mRNA. Translation takes place on ribosomes in the cell cytoplasm, where mRNA is read and translated into the string of amino acid chains that make up the synthesized protein.

The process of translation involves messenger RNA (mRNA), transfer RNA (tRNA), and ribosomal RNA (rRNA). Transfer RNAs, of tRNAs, connect mRNA codons to the amino acids they encode, while ribosomes are the structures where polypeptides (proteins) are built. Like transcription, translation also consists of three stages: initiation, elongation, and termination. In initiation, the ribosome assembles around the mRNA to be read and the first tRNA carrying the amino acid methionine. In elongation, the amino acid chain gets longer, and in termination, the finished polypeptide chain is released.

Fluoxetine can cause a serotonin syndrome when combined with sumatriptan due to their structural similarity and shared 5HT agonist properties. Agomelatine does not affect serotonin levels. Reboxetine works by inhibiting the reuptake of noradrenaline. To decrease the risk of serotonin syndrome, the dosage of fluoxetine can be reduced by 20 mg. Changing the form of fluoxetine to a liquid form would not significantly alter its bioavailability.

Enzymes called RNA polymerases, not transferases, transcribe RNA from DNA.

Common examples of acting out include avoiding therapy sessions and using alcohol as a means of avoiding the challenging work of therapy.

It allows the individual to avoid taking responsibility for their actions and to maintain a positive self-image.

Overall, rationalisation can be a useful defense mechanism in certain situations, but it can also be harmful if it leads to a lack of accountability and an inability to learn from mistakes.

Inheritance Patterns and Examples

Autosomal Dominant:
Neurofibromatosis type 1 and 2, tuberous sclerosis, achondroplasia, Huntington disease, and Noonan’s syndrome are all examples of conditions that follow an autosomal dominant inheritance pattern. This means that only one copy of the mutated gene is needed to cause the condition.

Autosomal Recessive:
Phenylketonuria, homocystinuria, Hurler’s syndrome, galactosaemia, Tay-Sach’s disease, Friedreich’s ataxia, Wilson’s disease, and cystic fibrosis are all examples of conditions that follow an autosomal recessive inheritance pattern. This means that two copies of the mutated gene are needed to cause the condition.

X-Linked Dominant:
Vitamin D resistant rickets and Rett syndrome are examples of conditions that follow an X-linked dominant inheritance pattern. This means that the mutated gene is located on the X chromosome and only one copy of the gene is needed to cause the condition.

X-Linked Recessive:
Cerebellar ataxia, Hunter’s syndrome, and Lesch-Nyhan are examples of conditions that follow an X-linked recessive inheritance pattern. This means that the mutated gene is located on the X chromosome and two copies of the gene are needed to cause the condition.

Mitochondrial:
Leber’s hereditary optic neuropathy and Kearns-Sayre syndrome are examples of conditions that follow a mitochondrial inheritance pattern. This means that the mutated gene is located in the mitochondria and is passed down from the mother to her offspring.

Mechanisms of Action of Different Drugs

Understanding the mechanisms of action of different drugs is crucial for medical professionals. It is a common topic in exams and can earn easy marks if studied well. This article provides a list of drugs and their mechanisms of action in different categories such as antidepressants, anti dementia drugs, mood stabilizers, anxiolytic/hypnotic drugs, antipsychotics, drugs of abuse, and other drugs.

The article also explains the mechanisms of action of drugs such as ketamine, phencyclidine, buprenorphine, naloxone, atomoxetine, varenicline, disulfiram, acamprosate, and sildenafil.

Understanding Bioavailability in Drug Trials

Bioavailability is a crucial factor in drug trials, as it determines the percentage of a drug that reaches the systemic circulation after administration. This can be affected by factors such as absorption and metabolic clearance. For example, if a drug called X is administered orally and only 60% reaches the systemic circulation, its bioavailability is 0.6 of 60%. However, if the same drug is administered intravenously, plasma levels may reach 100%.

One way to potentially increase bioavailability is through the rectal route, which bypasses around two thirds of the first-pass metabolism. This is because the rectum’s venous drainage is two thirds systemic (middle and inferior rectal vein) and one third portal (superior rectal vein). As a result, drugs administered rectally may reach the circulatory system with less alteration and in greater concentrations. Understanding bioavailability and exploring different administration routes can help optimize drug efficacy in clinical trials.

Liver consists of the sympathetic Alpha 1 and beta 2 receptors.

Regression to the mean is a statistical occurrence where the natural fluctuations in repeated data can appear as actual changes. This happens because measurements that are exceptionally high of low are typically followed by measurements that are closer to the average.

Understanding the Placebo Effect

In general, a placebo is an inert substance that has no pharmacological activity but looks, smells, and tastes like the active drug it is compared to. The placebo effect is the observable improvement seen when a patient takes a placebo, which results from patient-related factors such as expectations rather than the placebo itself. Negative effects due to patient-related factors are termed the nocebo effect.

Active placebos are treatments with chemical activity that mimic the side effects of the drug being tested in a clinical trial. They are used to prevent unblinding of the drug versus the placebo control group. Placebos need not always be pharmacological and can be procedural, such as sham electroconvulsive therapy.

The placebo effect is influenced by factors such as the perceived strength of the treatment, the status of the treating professional, and the branding of the compound. The placebo response is greater in mild illness, and the response rate is increasing over time. Placebo response is usually short-lived, and repeated use can lead to a diminished effect, known as placebo sag.

It is difficult to separate placebo effects from spontaneous remission, and patients who enter clinical trials generally do so when acutely unwell, making it challenging to show treatment effects. Breaking the blind may influence the outcome, and the expectancy effect may explain why active placebos are more effective than inert placebos. Overall, understanding the placebo effect is crucial in clinical trials and personalized medicine.

Heritability: Understanding the Concept

Heritability is a concept that is often misunderstood. It is not a measure of the extent to which genes cause a condition in an individual. Rather, it is the proportion of phenotypic variance attributable to genetic variance. In other words, it tells us how much of the variation in a condition seen in a population is due to genetic factors. Heritability is calculated using statistical techniques and can range from 0.0 to 1.0. For human behavior, most estimates of heritability fall in the moderate range of .30 to .60.

The quantity (1.0 – heritability) gives the environment ability of the trait. This is the proportion of phenotypic variance attributable to environmental variance. The following table provides estimates of heritability for major conditions:

Condition Heritability estimate (approx)
ADHD 85%
Autism 70%
Schizophrenia 55%
Bipolar 55%
Anorexia 35%
Alcohol dependence 35%
Major depression 30%
OCD 25%

It is important to note that heritability tells us nothing about individuals. It is a population-level measure that helps us understand the relative contributions of genetic and environmental factors to a particular condition.

The glossopharyngeal nerve is a mixed nerve consisting of both sensory and motor fibers. It has several branches and five distinct general functions:
Branchial motor- Special visceral efferent- supplies the Stylopharyngeus muscle and superior constrictor muscle.
Visceral motor- general visceral efferent- provides parasympathetic innervation of the parotid gland.
Visceral sensory- general visceral afferent- carries visceral sensory information from the carotid sinus and carotid body.
General sensory- general somatic afferent- provides general sensory information from the inner surface of the tympanic membrane, upper pharynx and posterior one third of the tongue.
Visceral afferent- special visceral afferent- provides taste sensation from the posterior one third of the tongue including the circumvallate papillae.

Brain Structures and Functions

The brain is a complex organ that is responsible for controlling various bodily functions. Among the important structures in the brain are the substantia nigra, hippocampus, hypothalamus, pituitary gland, and thalamus.

The substantia nigra is a part of the basal ganglia located in the midbrain. It contains dopamine-producing neurons that regulate voluntary movement and mood. Parkinson’s disease is associated with the degeneration of the melanin-containing cells in the pars compacta of the substantia nigra.

The hippocampus is a part of the limbic system that is involved in memory, learning, attention, and information processing.

The hypothalamus is located at the base of the brain near the pituitary gland. It regulates thirst, hunger, circadian rhythm, emotions, and body temperature. It also controls the pituitary gland by secreting hormones.

The pituitary gland is a small endocrine organ located below the hypothalamus in the middle of the base of the brain. It controls many bodily functions through the action of hormones and is divided into an anterior lobe, intermediate lobe, and posterior lobe.

The thalamus is located above the brainstem and processes and relays sensory and motor information.

Research has consistently shown that out-patient services, whether they are general of specialized eating disorder clinics, are more likely to be cost-effective than in-patient care. The majority of patients with eating disorders can be effectively managed in out-patient clinics, with only a small percentage requiring in-patient care. When comparing outpatient treatment models, including general child and adolescent mental health services, with in-patient treatment, there were significant improvements in all groups at different points during follow-up, with no significant differences between the two types of treatment. The availability of out-patient care is associated with a lower rate of admission to inpatient units. Clinically and economically, lengthy in-patient stays are not recommended, as they are associated with worse outcomes, particularly when they disrupt the patient’s life, such as their work, studies, of time away from family.

To ensure adherence, it is crucial to prescribe medication based on the individual’s needs to prevent sexual issues. Among the options provided, mirtazapine has the least occurrence of sexual dysfunction.

Antidepressants can cause sexual dysfunction as a side-effect, although the rates vary. The impact on sexual desire, arousal, and orgasm can differ depending on the type of antidepressant. It is important to rule out other causes and consider non-pharmacological strategies such as reducing the dosage of taking drug holidays. If necessary, switching to a lower risk antidepressant of using pharmacological options such as phosphodiesterase inhibitors of mirtazapine augmentation can be considered. The Maudsley Guidelines 14th Edition provides a helpful table outlining the risk of sexual dysfunction for different antidepressants.

Agnosia is a condition where a person loses the ability to recognize objects, persons, sounds, shapes, of smells, despite having no significant memory loss of defective senses. There are different types of agnosia, such as prosopagnosia (inability to recognize familiar faces), anosognosia (inability to recognize one’s own condition/illness), autotopagnosia (inability to orient parts of the body), phonagnosia (inability to recognize familiar voices), simultanagnosia (inability to appreciate two objects in the visual field at the same time), and astereoagnosia (inability to recognize objects by touch).

Suboxone vs. Subutex: What’s the Difference?

Suboxone and Subutex are both medications used to treat opioid addiction. However, there are some key differences between the two.

Suboxone is a combination of buprenorphine and naloxone. The naloxone is added to prevent people from injecting the medication, as this was a common problem with pure buprenorphine tablets. If someone tries to inject Suboxone, the naloxone will cause intense withdrawal symptoms. However, if the tablet is swallowed as directed, the naloxone is not absorbed by the gut and does not cause any problems.

Subutex, on the other hand, contains only buprenorphine and does not include naloxone. This means that it may be more likely to be abused by injection, as there is no deterrent to prevent people from doing so.

Overall, both Suboxone and Subutex can be effective treatments for opioid addiction, but Suboxone may be a safer choice due to the addition of naloxone.

The belief that her neighbors are spying on her, which was triggered by the TV, is likely a secondary delusion stemming from a pathological encounter such as a hallucination of a referential experience.

Borderline Learning Disability

Borderline learning disability is a term used to describe individuals with an IQ between 70-85. This category is not officially recognized as a diagnosis by the ICD-11. It is estimated that approximately 15% of the population falls within this range (Chaplin, 2005). Unlike mild learning disability, borderline learning disability is not typically associated with deficits in adaptive functioning, such as grooming, dressing, safety, of money management.

Apraxia is the inability to perform voluntary actions despite having intact neurological function. Agnosia is the inability to comprehend the meaning of sensory input despite having intact neurological function. Astereognosia is the inability to recognize three-dimensional shapes, while agraphoagnosia is the inability to recognize numbers traced on the palm. Atopognosia is the inability to identify the location of an object on the skin, and constructional apraxia is the inability to draw simple figures. Ideomotor apraxia is the inability to perform a skilled action in response to verbal commands of imitation, although the ability to perform actions spontaneously with tools may remain intact.
