ICD-11 Criteria for Schizoaffective Disorder (6A21)

Schizoaffective disorder is an episodic disorder in which the diagnostic requirements of schizophrenia and a manic, mixed, or moderate or severe depressive episode are met within the same episode of illness, either simultaneously or within a few days of each other. Prominent symptoms of schizophrenia (e.g. delusions, hallucinations, disorganisation in the form of thought, experiences of influence, passivity and control) are accompanied by typical symptoms of a moderate or severe depressive episode (e.g. depressed mood, loss of interest, reduced energy), a manic episode (e.g. an extreme mood state characterised by euphoria, irritability, or expansiveness; increased activity or a subjective experience of increased energy) or a mixed episode. Psychomotor disturbances, including catatonia, may be present. Symptoms must have persisted for at least one month. The symptoms are not a manifestation of another medical condition (e.g. a brain tumor) and are not due to the effect of a substance or medication on the central nervous system (e.g. corticosteroids), including withdrawal (e.g. alcohol withdrawal).

ADVOKATE: A Mnemonic Tool for the Assessment of Eyewitness Evidence

By
ADVOKATE: A Mnemonic Tool for Assessment of Eyewitness Evidence A tool for assessing eyewitness  ADVOKATE is a tool designed to assess eyewitness evidence and how much it is reliable. It requires the user to respond to several statements/questions. Forensic psychologists, police or investigative officer can do it. The mnemonic ADVOKATE stands for: A = amount of time under observation (event and act) D = distance from suspect V = visibility (night-day, lighting) O = obstruction to the view of the witness K = known or seen before when and where (suspect) A = any special reason for remembering the subject T = time-lapse (how long has it been since witness saw suspect) E = error or material discrepancy between the description given first or any subsequent accounts by a witness.  Working with suspects (college.police.uk)

By
ICD-11 Criteria for Attention Deficit Hyperactivity Disorder (ADHD) 6A05 Attention deficit hyperactivity disorder is characterised by a persistent pattern (at least 6 months) of inattention and/or hyperactivity-impulsivity that has a direct negative impact on academic, occupational, or social functioning. There is evidence of significant inattention and/or hyperactivity-impulsivity symptoms prior to age 12, typically by early to mid-childhood, though some individuals may first come to clinical attention later. The degree of inattention and hyperactivity-impulsivity is outside the limits of normal variation expected for age and level of intellectual functioning. Inattention refers to significant difficulty in sustaining attention to tasks that do not provide a high level of stimulation or frequent rewards, distractibility and problems with organisation. Hyperactivity refers to excessive motor activity and difficulties with remaining still, most evident in structured situations that re...
