Disruption in the form or flow of thinking, evident in speech that is derailed, tangential, incoherent, or pressured, most classically associated with schizophrenia and mania.
- First-rank symptoms
- Related: Thought disorder, Psychosis
Schneiderian phenomena such as audible thoughts, voices arguing or commenting, thought insertion or withdrawal, made feelings and impulses, and delusional perception, historically regarded as strongly suggestive of schizophrenia.
- Formal thought disorder rating
- Related: Thought disorder
Structured assessment of the form of speech and thinking, for example using the Thought and Language Index, distinguishing positive features such as derailment from negative features such as poverty of speech.
- Psychosis
- Related: First-rank symptoms, Delirium
A state of impaired reality testing marked by hallucinations, delusions, or disorganised thinking, with reduced insight, arising from primary psychiatric illness, substances, or medical causes.
- Insight
- Related: Consent and capacity, Psychosis
A person's awareness of having an illness, of its nature and cause, and of the need for treatment; poor insight predicts non-adherence and is common in psychotic disorders.
- Consent and capacity
- Related: Insight, Delirium
Valid consent requires information, voluntariness, and decision-making capacity: the ability to understand, retain, weigh, and communicate a decision about the specific proposed treatment.
- Serotonin syndrome
- Related: Delirium, Neuroleptic malignant syndrome
A potentially fatal toxidrome of autonomic instability, neuromuscular hyperactivity such as clonus and hyperreflexia, and altered mental state, caused by serotonergic excess, often from drug combinations.
- Neuroleptic malignant syndrome
- Related: Serotonin syndrome, Catatonia
A rare idiosyncratic reaction to dopamine antagonists featuring rigidity, hyperthermia, autonomic instability, and altered consciousness, with raised creatine kinase, requiring drug cessation and supportive care.
- QTc interval
- Related: Clozapine monitoring
The heart-rate-corrected QT interval on ECG; prolongation above roughly 450–500 ms raises the risk of torsades de pointes, relevant to antipsychotics, some antidepressants, and methadone.
- Clozapine monitoring
- Related: QTc interval, Treatment-resistant schizophrenia
Mandatory regular full blood counts for agranulocytosis risk, plus checks of troponin, weight, glucose, and lipids, with dose titration and caution regarding constipation and myocarditis.
- Treatment-resistant schizophrenia
- Related: Clozapine monitoring
Schizophrenia with persistent, clinically significant symptoms despite adequate trials of at least two different antipsychotics at therapeutic doses for sufficient duration, typically prompting a clozapine trial.
- Electroconvulsive therapy
- Related: Catatonia, Treatment-resistant schizophrenia
A controlled general-anaesthetic procedure delivering brief electrical stimulation to induce a seizure, used for severe depression, catatonia, and other acute conditions, with cognitive side effects as the main limitation.
- Lithium toxicity
- Related: QTc interval
Clinical features such as tremor, ataxia, confusion, vomiting, and seizures when serum lithium rises, commonly triggered by dehydration, renal impairment, or interacting drugs; management includes dialysis in severe cases.
- Therapeutic alliance
- Related: Transference, Mentalization
The collaborative emotional bond and agreement on goals and tasks between clinician and patient, consistently predictive of psychotherapy outcome across modalities.
- Transference
- Related: Therapeutic alliance, Countertransference
The displacement onto the clinician of feelings, expectations, and relational patterns originally linked to significant figures from the patient's past, used as clinical material in psychodynamic work.
- Countertransference
- Related: Transference
The clinician's emotional responses to the patient, which may reflect the patient's relational impact or the clinician's own unresolved conflicts and can inform or distort treatment.
- Mentalization
- Related: Therapeutic alliance, Transference
The capacity to understand one's own and others' behaviour in terms of underlying mental states, which is impaired under stress and is a target of mentalization-based treatment for borderline personality disorder.
- Cognitive restructuring
- Related: Exposure therapy
A cognitive therapy technique that identifies and tests the evidence for and against unhelpful automatic thoughts and beliefs, then develops balanced alternatives.
- Exposure therapy
- Related: Cognitive restructuring
Systematic, repeated, and prolonged confrontation with feared stimuli without avoidance, allowing anxiety to habituate or inhibitory learning to occur; a first-line treatment for anxiety disorders and OCD.
- Attention-deficit/hyperactivity disorder
- Related: Conduct disorder, Separation anxiety disorder
A persistent pattern of inattention and/or hyperactivity-impulsivity, present before age twelve and causing impairment across settings, treated with behavioural strategies and stimulant or non-stimulant medication.
- Conduct disorder
- Related: Attention-deficit/hyperactivity disorder, Fitness to stand trial
A repetitive pattern of behaviour violating others' rights or major age-appropriate norms, such as aggression, theft, and rule-breaking, with high overlap with callous-unemotional traits and later antisocial personality disorder.
- Separation anxiety disorder
- Related: Attention-deficit/hyperactivity disorder
Developmentally inappropriate, persistent distress about separation from attachment figures, with worry about harm befalling them, refusal of school or sleepovers, and physical symptoms.
- Delirium superimposed on dementia
- Related: Delirium, Behavioural and psychological symptoms of dementia
Acute worsening of attention and awareness in a person with established cognitive impairment; recognition requires knowing baseline function and is often missed in older inpatients.
- Behavioural and psychological symptoms of dementia
- Related: Delirium superimposed on dementia
Non-cognitive features such as agitation, psychosis, apathy, and sleep disturbance in dementia, managed first with environmental and psychosocial measures, reserving medication for severe or dangerous symptoms.
- Fitness to stand trial
- Related: Conduct disorder, Not guilty by reason of mental impairment
The defendant's present ability to understand the charges and proceedings and to instruct counsel; unfitness is usually temporary and addressed through treatment or diversion rather than a verdict on guilt.
- Not guilty by reason of mental impairment
- Related: Fitness to stand trial
A verdict that the accused committed the act but was, at the time, suffering a mental impairment depriving them of the capacity to know the nature of the act or that it was wrong, leading to supervision rather than punishment.
- Risk assessment
- Related: Not guilty by reason of mental impairment
Structured estimation of the likelihood and nature of future harm, combining actuarial tools with clinical judgement and dynamic factors, and linked to management planning rather than prediction alone.
- Alcohol withdrawal
- Related: Wernicke encephalopathy, Delirium
A time-limited syndrome after cessation or reduction of heavy alcohol use, ranging from tremor and anxiety to seizures and delirium tremens, managed with benzodiazepines, thiamine, and supportive care.
- Wernicke encephalopathy
- Related: Alcohol withdrawal
A thiamine-deficiency emergency causing ophthalmoplegia, ataxia, and confusion, common in alcohol use disorder and malnutrition; untreated it can progress to Korsakoff syndrome.
- Opioid substitution treatment
- Related: Alcohol withdrawal, QTc interval
Prescribing a long-acting opioid agonist such as methadone or buprenorphine to reduce illicit use, craving, and overdose risk, with supervised dosing and psychosocial support.
- Dopamine hypothesis
- Related: Psychosis, Treatment-resistant schizophrenia
The proposal that positive psychotic symptoms arise from excessive mesolimbic dopamine transmission, supported by antipsychotic potency and stimulant effects, though it does not fully explain negative and cognitive symptoms.
- Hypothalamic-pituitary-adrenal axis
- Related: Serotonin syndrome
The endocrine stress system in which hypothalamic corticotropin-releasing hormone drives pituitary ACTH and adrenal cortisol release, implicated in mood and anxiety disorders and in cognitive effects of chronic stress.
- Neuroplasticity
- Related: Dopamine hypothesis
The brain's capacity to modify synaptic connections and structure in response to experience, learning, injury, and treatment, underpinning recovery and the effects of psychotherapy.
