Bowlby’s attachment theory suggests that social relationships are formed based on the biological and psychological needs of both the mother and the infant. During the first year of life, attachment development is crucial, and infants begin to form selective attachments to individuals, typically starting with the mother. The interaction between the mother and infant is essential in promoting social relationships. In 1945, Rene Spitz coined the term hospitalism to describe the negative effects of institutionalization and maternal deprivation on young children’s development. These children failed to thrive, despite receiving adequate nutrition and healthcare, and experienced high mortality, morbidity, and severe psychopathology. Bowlby also identified separation anxiety as the fear infants exhibit when separated from their caregiver. Margaret Mahler’s separation-individuation theory explains the process by which individuals emerge as separate entities, both intrapsychically and interpersonally.

The question pertains to a classic case of atypical depression, which is best treated with phenelzine, a MAOI. While imipramine and other TCAs have some evidence for treating atypical depression, they are not as effective as MAOIs. Nowadays, SSRIs are commonly used as a first-line treatment, but they have a weaker evidence base compared to MAOIs and TCAs. Vortioxetine is a new antidepressant that has complex effects on the 5HT system, but it has not been studied for its efficacy in treating atypical depression. Similarly, venlafaxine has not been studied for this indication either.

Delirium Management

Pharmacological management of delirium includes the use of haloperidol as a prophylactic measure. NICE guidelines recommend short-term use of haloperidol in cases where delirium is associated with distress of risk to self/others. Quetiapine is also considered a first-choice option in many units. Lorazepam can be used as an alternative if haloperidol is contraindicated, but it is more likely to cause respiratory depression, over-sedation, and paradoxical excitement.

Non-pharmacological management of delirium includes appropriate lighting and clear signage, talking to the person to reorient them, cognitively stimulating activities, regular visits from family and friends, and promoting good sleep patterns. Additional options such as donepezil, rivastigmine, melatonin, trazodone, and sodium valproate are not recommended. It is important to carefully consider the individual’s needs and medical history when choosing a management plan for delirium.

If the individual were to experience impaired consciousness during the attack, this would be classified as a complex partial seizure. However, based on the current symptoms, it appears to be a simple partial seizure with retained consciousness.

Lurasidone may cause akathisia and sedation as common side effects, which can vary based on the dosage. Its metabolic profile is neutral. However, doses lower than 37 mg are unlikely to produce desired results.

Ross proposed the idea of prima facie duties, which were later modified by Beauchamp and Childress to form the four principles approach to medical ethics. The prima facie duties identified by Ross encompassed fidelity, reparation, gratitude, non-injury, harm-prevention, beneficence, self-improvement, and justice.

Ethical theory and principles are important in medical ethics. There are three key ethical theories that have dominated medical ethics: utilitarianism, deontological, and virtue-based. Utilitarianism is based on the greatest good for the greatest number and is a consequentialist theory. Deontological ethics emphasize moral duties and rules, rather than consequences. Virtue ethics is based on the ethical characteristics of a person and is associated with the concept of a good, happy, flourishing life.

More recent frameworks have attempted to reconcile different theories and values. The ‘four principles’ of ‘principlism’ approach, developed in the United States, is based on four common, basic prima facie moral commitments: autonomy, beneficence, non-maleficence, and justice. Autonomy refers to a patient’s right to make their own decisions, beneficence refers to the expectation that a doctor will act in a way that will be helpful to the patient, non-maleficence refers to the fact that doctors should avoid harming their patients, and justice refers to the expectation that all people should be treated fairly and equally.

The women’s movements are being narrated in real-time by the voices, which is known as ‘running commentary’. It does not appear that the voices are affecting her thoughts in any way.

First Rank Symptoms: Their Significance in Identifying Schizophrenia

First rank symptoms were introduced by Kurt Schneider in 1938 as a practical tool for non-psychiatrists to identify schizophrenia. While they are highly suggestive of schizophrenia, they are not pathognomonic and can also be seen in affective and personality disorders. Additionally, there is no evidence to support their prognostic significance.

A systematic review in 2015 found that first rank symptoms differentiated schizophrenia from nonpsychotic mental health disorders with a sensitivity of 61.8% and a specificity of 94.1%. They also differentiated schizophrenia from other types of psychosis with a sensitivity of 58% and a specificity of 74.7%.

The first rank symptoms include running commentary, thought echo, voices heard arguing, thought insertion, thought withdrawal, thought broadcast, delusional perception, somatic passivity, made affect, and made volition. While they can be helpful in identifying schizophrenia, they should not be relied upon as the sole diagnostic criteria.

The AUDIT is a screening tool consisting of 10 items that can quickly identify potential alcohol problems. Similarly, the AQ-10 is a 10 item scale used to measure autism quotient. The CAGE is a four item screening tool for alcohol problems, while the CIWA is a scale used to assess alcohol withdrawal. The PHQ-9, commonly used in general practice, is the personal health questionnaire.

Autism: A Brief History

The term autism was first coined in 1911 by Eugen Bleuler to describe individuals with schizophrenia who had cut themselves off as much as possible from any contact with the external world. In 1926, Grunya Sukhareva attempted to delineate autism spectrum disorders as distinct diagnostic entities, referring to them as schizoid personality disorder. However, her work remained largely unknown until 1996.

The first widely publicized use of the term autism to describe a distinct condition was in 1943 by Leo Kanner, who referred to it as autistic disturbance of affective contact. Kanner suggested that autism may be a manifestation of childhood schizophrenia and that it was characterized by an inability to related to themselves in the ordinary way to people and situations from the beginning of life. In 1944, Hans Asperger published descriptions of four cases of a condition he termed der autistichen psychopathie, which he regarded as a limitation of social relationships.

In 1980, infantile autism was included in the DSM-III under a new category of pervasive developmental disorders. Lorna Wing redefined Asperger Syndrome in 1981, proposing a triad of impairments in social interaction, communication, and imaginative activities. In 2000, the DSM-IV utilized the umbrella category of pervasive developmental disorders, with five main subcategories. Finally, in 2013, the DSM-5 combined the subcategories into a single label of autism spectrum disorder, asserting that autism is a single disorder on a wide spectrum.

Autism and Genetics

Research has shown that there is a strong genetic component to autism. In fact, siblings of individuals with autism are significantly more likely to develop the disorder than someone in the general population. Twin studies have also demonstrated the high heritability of autism, but have also highlighted the genetic complexity of the disorder. Monozygotic twins have a concordance rate of 60-90%, while dizygotic twins have a concordance rate closer to 30%. Despite this, the molecular genetics of autism is still not well understood. Copy number variations (CNVs) have been implicated, along with a number of candidate genes. Further research is needed to fully understand the genetic basis of autism.

Folie a deux is a type of shared psychosis where a mentally healthy person adopts the delusional beliefs of a mentally ill person with whom they have a close relationship. The mentally ill person is the primary individual with the delusion, while the mentally healthy person is the secondary individual who acquires the delusion. There are four different types of relationships between the primary and secondary individuals: folie imposée, folie communiqué, folie induite, and folie simultanée. In folie imposée, the delusions of the mentally ill person are imposed on the mentally healthy person, who may have some social of psychological disadvantage. In folie communiqué, the mentally healthy person initially resists the delusion but eventually adopts it and maintains it even after separation from the mentally ill person. In folie induite, a person who is already psychotic incorporates the delusions of a closely associated primary individual into their own delusional system. In folie simultanée, two of more people become psychotic and share the same delusional system at the same time.

Erik Erikson and Daniel Levinson expanded the understanding of adult development. Erikson proposed a life-span model of human development consisting of eight successive psychosocial stages, each associated with an inherent conflict of crisis that the individual must encounter and successfully resolve to proceed with development. Levinson proposed a developmental theory consisting of universal stages of phases that extend from the infancy state to the elderly state, based on biographical interviews of 40 men in America. Both theorists maintained that personality develops in a predetermined order and builds upon each previous stage, and that failure to successfully negotiate a stage can result in a reduced ability to complete further stages and therefore a more unhealthy personality and sense of self. However, Levinson’s theory is age-based rather than event-based, and his model proposed a ‘life sequence’ consisting of a series of alternating stable (structure-building) periods and cross-era transitional (structure-changing) periods, with transitional periods typically lasting 5 years.

It is not recommended to combine MAOIs with SSRIs, clomipramine, of ephedrine.

MAOIs: A Guide to Mechanism of Action, Adverse Effects, and Dietary Restrictions

First introduced in the 1950s, MAOIs were the first antidepressants introduced. However, they are not the first choice in treating mental health disorders due to several dietary restrictions and safety concerns. They are only a treatment option when all other medications are unsuccessful. MAOIs may be particularly useful in atypical depression (over eating / over sleeping, mood reactivity).

MAOIs block the monoamine oxidase enzyme, which breaks down different types of neurotransmitters from the brain: norepinephrine, serotonin, dopamine, as well as tyramine. There are two types of monoamine oxidase, A and B. The MOA A are mostly distributed in the placenta, gut, and liver, but MOA B is present in the brain, liver, and platelets. Selegiline and rasagiline are irreversible and selective inhibitors of MAO type B, but safinamide is a reversible and selective MAO B inhibitor.

The most common adverse effects of MAOIs occurring early in treatment are orthostatic hypotension, daytime sleepiness, insomnia, and nausea; later common effects include weight gain, muscle pain, myoclonus, paraesthesia, and sexual dysfunction.

Pharmacodynamic interactions with MAOIs can cause two types of problem: serotonin syndrome (mainly due to SSRIs) and elevated blood pressure (caused by indirectly acting sympathomimetic amines releasers, like pseudoephedrine and phenylephrine). The combination of MAOIs and some TCAs appears safe. Only those TCAs with significant serotonin reuptake inhibition (clomipramine and imipramine) are likely to increase the risk of serotonin syndrome.

Tyramine is a monoamine found in various foods, and is an indirect sympathomimetic that can cause a hypertensive reaction in patients receiving MAOI therapy. For this reason, dietary restrictions are required for patients receiving MAOIs. These restrictions include avoiding matured/aged cheese, fermented sausage, improperly stored meat, fava of broad bean pods, and certain drinks such as on-tap beer. Allowed foods include fresh cottage cheese, processed cheese slices, fresh packaged of processed meat, and other alcohol (no more than two bottled or canned beers of two standard glasses of wine, per day).

Thyroid disease is typically linked with pretibial myxoedema.

Hepatomegaly

Chronic alcohol abuse can lead to hepatomegaly, which is an enlargement of the liver. This can be detected on physical examination by palpating the liver below the right ribcage. Hepatomegaly can also be associated with other signs of liver disease, such as jaundice, spider naevi, and caput medusa. It is important for psychiatrists to be aware of these physical findings in patients with alcohol use disorder, as they may indicate the need for further medical evaluation and treatment.

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.

Pregabalin: Pharmacokinetics and Mechanism of Action

Pregabalin is a medication that acts on the alpha-2-delta subunit of voltage-gated calcium channels in the central nervous system. It is known for its anticonvulsant, analgesic, and anxiolytic properties. By decreasing presynaptic calcium currents, it reduces the release of excitatory neurotransmitters that contribute to anxiety. Despite being a GABA analogue, it does not affect GABA receptors of metabolism.

Pregabalin has predictable and linear pharmacokinetics, making it easy to use in clinical practice. It is rapidly absorbed and proportional to dose, with a time to maximal plasma concentration of approximately 1 hour. Steady state is achieved within 24-48 hours, and efficacy can be observed as early as day two in clinical trials. It has a high bioavailability and a mean elimination half-life of 6.3 hours.

Unlike many medications, pregabalin is not subject to hepatic metabolism and does not induce of inhibit liver enzymes such as the cytochrome P450 system. It is excreted unchanged by the kidneys and does not bind to plasma proteins. This means that it is unlikely to cause of be affected by pharmacokinetic drug-drug interactions.

While there is some potential for abuse of pregabalin, the euphoric effects disappear with prolonged use. Overall, pregabalin is a safe and effective medication for the treatment of various conditions, including anxiety and neuropathic pain.

The projective approach to personality assessment utilizes ambiguous test stimuli to reveal information about an individual’s personality. The Rorschach test, which involves ten inkblot cards, is the most widely used and researched projective test. The Thematic Apperception Test (TAT) is another projective measure that uses 20 stimulus cards depicting ambiguous scenes. The Make a Picture Story (MAPS) test is similar to the TAT but allows the patient to manage the stimuli. In contrast, the Minnesota Multiphasic Personality Inventory (MMPI) and the Personality Assessment Inventory (PAI) are objective measures of personality in adults.

Multisystem Atrophy: A Parkinson Plus Syndrome

Multisystem atrophy is a type of Parkinson plus syndrome that is characterized by three main features: Parkinsonism, autonomic failure, and cerebellar ataxia. It can present in three different ways, including Shy-Drager Syndrome, Striatonigral degeneration, and Olivopontocerebellar atrophy, each with varying degrees of the three main features.

Macroscopic features of multisystem atrophy include pallor of the substantia nigra, greenish discoloration and atrophy of the putamen, and cerebellar atrophy. Microscopic features include the presence of Papp-Lantos bodies, which are alpha-synuclein inclusions found in oligodendrocytes in the substantia nigra, cerebellum, and basal ganglia.

Overall, multisystem atrophy is a complex and debilitating condition that affects multiple systems in the body, leading to a range of symptoms and challenges for patients and their caregivers.

When treating catatonia, the preferred initial treatment is benzodiazepines such as lorazepam. If this approach is unsuccessful, electroconvulsive therapy (ECT) should be considered.

Catatonia Treatment

Catatonia can lead to complications such as dehydration, deep vein thrombosis, pulmonary embolism, and pneumonia. Therefore, prompt treatment is essential. The first-line treatment is benzodiazepines, particularly lorazepam. If this is ineffective, electroconvulsive therapy (ECT) may be considered. The use of antipsychotics is controversial and should be avoided during the acute phase of catatonia.

Piaget’s Stages of Development and Key Concepts

Piaget developed four stages of development that describe how children think and acquire knowledge. The first stage is the Sensorimotor stage, which occurs from birth to 18-24 months. In this stage, infants learn through sensory observation and gain control of their motor functions through activity, exploration, and manipulation of the environment.

The second stage is the Preoperational stage, which occurs from 2 to 7 years. During this stage, children use symbols and language more extensively, but they are unable to think logically of deductively. They also use a type of magical thinking and animistic thinking.

The third stage is the Concrete Operational stage, which occurs from 7 to 11 years. In this stage, egocentric thought is replaced by operational thought, which involves dealing with a wide array of information outside the child. Children in this stage begin to use limited logical thought and can serialise, order, and group things into classes on the basis of common characteristics.

The fourth and final stage is the Formal Operations stage, which occurs from 11 through the end of adolescence. This stage is characterized by the ability to think abstractly, to reason deductively, to define concepts, and also by the emergence of skills for dealing with permutations and combinations.

Piaget also developed key concepts, including schema, assimilation, and accommodation. A schema is a category of knowledge and the process of obtaining that knowledge. Assimilation is the process of taking new information into an existing schema, while accommodation involves altering a schema in view of additional information.

Overall, Piaget’s stages of development and key concepts provide a framework for understanding how children learn and acquire knowledge.

– Catatonia is a psychiatric syndrome characterized by disturbed motor functions, mood, and thought.
– Key behaviors associated with catatonia include stupor, posturing, waxy flexibility, negativism, automatic obedience, mitmachen, mitgehen, ambitendency, psychological pillow, forced grasping, obstruction, echopraxia, aversion, mannerisms, stereotypies, motor perseveration, echolalia, and logorrhoea.
– These behaviors are often tested in exam questions.
– Karl Ludwig Kahlbaum is credited with the original clinical description of catatonia.

Delayed Seizures in Metrazol-Induced Convulsions

During the early development of electroconvulsive therapy (ECT), chemical convulsions using Metrazol were commonly used. However, this method was associated with a high risk of fractures due to the violent seizures induced. To address this issue, various forms of muscle relaxation were introduced, leading to the replacement of chemical convulsions with ECT.

Despite the risks associated with Metrazol-induced convulsions, they were noted to be effective for severe depression. However, delayed seizures were a common occurrence with this method.

The capacity of an individual to make decisions is specific to the decision being made and can change over time. The Mental Capacity Act 2005 aims to protect and empower those who may lack capacity to make certain decisions. The Act is based on five key principles, including the assumption that every adult has the right to make their own decisions unless proven otherwise, the provision of practical help before assuming lack of capacity, and the importance of making decisions in the best interests of the individual. Additionally, any actions taken on behalf of someone lacking capacity should be the least restrictive of their basic rights and freedoms. It is important to note that an unwise decision does not necessarily indicate a lack of capacity.

First Rank Symptoms: Their Significance in Identifying Schizophrenia

First rank symptoms were introduced by Kurt Schneider in 1938 as a practical tool for non-psychiatrists to identify schizophrenia. While they are highly suggestive of schizophrenia, they are not pathognomonic and can also be seen in affective and personality disorders. Additionally, there is no evidence to support their prognostic significance.

A systematic review in 2015 found that first rank symptoms differentiated schizophrenia from nonpsychotic mental health disorders with a sensitivity of 61.8% and a specificity of 94.1%. They also differentiated schizophrenia from other types of psychosis with a sensitivity of 58% and a specificity of 74.7%.

The first rank symptoms include running commentary, thought echo, voices heard arguing, thought insertion, thought withdrawal, thought broadcast, delusional perception, somatic passivity, made affect, and made volition. While they can be helpful in identifying schizophrenia, they should not be relied upon as the sole diagnostic criteria.

Reticulospinal tract pass down from the reticular formation of the mid brain, pons and medulla. It descends in the lateral white column. Both sets of fibers enter the anterior grey column and may facilitate or inhibit the gamma and alpha neurons. By this means the reticulospinal tract controls voluntary and reflex activities. It also contains the descending autonomic fiber, thus providing a pathway for the hypothalamus to control the sympathetic and parasympathetic pathways.

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.

The Dunning-Kruger effect refers to a phenomenon where individuals with lower levels of skill of knowledge tend to overestimate their abilities, leading them to believe they are more competent than they actually are.

The Flynn Effect is the term used to describe the increase in standardised intelligence test scores over time. Research conducted by Flynn showed that IQ scores increased by 13.8 points between 1932 and 1978, which equates to a 0.3-point increase per year of approximately 3 points per decade. More recent studies have also supported the Flynn effect, with IQ score gains observed between 1972 and 2006. This means that an individual is likely to achieve a higher IQ score on an earlier version of a test than on the current version. In fact, the test will overestimate an individual’s IQ score by an average of 0.3 points per year between the year in which the test was normed and the year in which the test was administered.

Serotonin: Synthesis and Breakdown

Serotonin, also known as 5-Hydroxytryptamine (5-HT), is synthesized in the central nervous system (CNS) in the raphe nuclei located in the brainstem, as well as in the gastrointestinal (GI) tract in enterochromaffin cells. The amino acid L-tryptophan, obtained from the diet, is used to synthesize serotonin. L-tryptophan can cross the blood-brain barrier, but serotonin cannot.

The transformation of L-tryptophan into serotonin involves two steps. First, hydroxylation to 5-hydroxytryptophan is catalyzed by tryptophan hydroxylase. Second, decarboxylation of 5-hydroxytryptophan to serotonin (5-hydroxytryptamine) is catalyzed by L-aromatic amino acid decarboxylase.

Serotonin is taken up from the synapse by a monoamine transporter (SERT). Substances that block this transporter include MDMA, amphetamine, cocaine, TCAs, and SSRIs. Serotonin is broken down by monoamine oxidase (MAO) and then by aldehyde dehydrogenase to 5-Hydroxyindoleacetic acid (5-HIAA).

A diagnosis of reactive attachment disorder cannot be made until the child reaches at least one year of age.

Disorders resulting from inadequate caregiving during childhood are recognised by both the DSM-5 and the ICD-11, with two distinct forms of disorder identified: Reactive attachment disorder and Disinhibited social engagement disorder. Reactive attachment disorder is characterised by social withdrawal and aberrant attachment behaviour, while Disinhibited social engagement disorder is characterised by socially disinhibited behaviour. Diagnosis of these disorders involves a history of grossly insufficient care, and symptoms must be evident before the age of 5. Treatment options include video feedback programs for preschool aged children and parental training with group play sessions for primary school aged children. Pharmacological interventions are not recommended in the absence of coexisting mental health problems.

Adults require a minimum effective dose of 20 mg of fluoxetine.

Antidepressants: Minimum Effective Doses

According to the Maudsley 13th, the following are the minimum effective doses for various antidepressants:

– Citalopram: 20 mg/day
– Fluoxetine: 20 mg/day
– Fluvoxamine: 50 mg/day
– Paroxetine: 20 mg/day
– Sertraline: 50 mg/day
– Mirtazapine: 30 mg/day
– Venlafaxine: 75 mg/day
– Duloxetine: 60 mg/day
– Agomelatine: 25 mg/day
– Moclobemide: 300 mg/day
– Trazodone: 150 mg/day

Note that these are minimum effective doses and may vary depending on individual factors and response to treatment. It is important to consult with a healthcare professional before starting of changing any medication regimen.
