Glutamate Antagonists for the Treatment of Catatonia

Because of its N-methyl-d-aspartic acid antagonist properties, amantadine (100–500mg three times a day), and its derivative memantine (5–20mg/day), have been tried in catatonia.

  1. Carroll and coworkers identified 25 cases of amantadine and memantine use in the treatment of catatonia. All cases improved, mostly after 1–7days.

  2. It should be noted, however, that six were unpublished, and that seven other were cases experiencing a “catatonia-parkinsonian syndrome” while under treatment with the high-potency neuroleptic drugs haloperidol or fluphenazine.
  3. The symptoms diminished when neuroleptics were tapered, and they added amantadine. Since then, they have published eleven additional cases describing the successful use of amantadine or memantine in catatonia.
  4. In one case, in an adolescent girl, catatonia that was resistant to ECT improved after the addition of amantadine.
  5. Only in a review of Hawkins and coworkers, they report a case in which the use of amantadine remained without effect. Should acknowledge, however, that negative cases are less likely to be published.
  6. Given these positive signals in the published literature, and evidence of its efficacy in treating the negative and cognitive symptoms of schizophrenia, amantadine should be further studied as a feasible treatment option for catatonia. There is anecdotal evidence from case reports on the use of various other pharmacological agents, such as bromocriptine and biperiden.
  7. Based on the GABA-hypothesis of catatonia, and the GABA-related working mechanism of several anti-convulsive mood stabilizers, these drugs have been proposed as a viable treatment option to treat catatonia in bipolar patients.
  8. Only a few cases have published reports.
  9. They used valproate in several case reports and found not only to have prophylactic effects but also “an improving effect on the catatonic symptoms”.
  10. In a solitary case report, they advocated levetiracetam as a treatment for catatonia in bipolar disorder, given its mood-stabilizing efficacy.
  11. It is of note, however, that levetiracetam has also been described to provoke catatonia.
  12. Using topiramate and carbamazepine have also been reported.
  13. Although lithium has been anecdotally reported to have a beneficial effect on acute catatonic symptoms, they mostly describe it to be of use in the prevention of recurrent catatonia, albeit with sometimes limited results.

ADVOKATE: A Mnemonic Tool for the Assessment of Eyewitness Evidence

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 (

ICD-11 Criteria for Anorexia Nervosa (6B80)

ICD-11 Criteria for Anorexia Nervosa (6B80) Anorexia Nervosa is characterised by significantly low body weight for the individual’s height, age and developmental stage that is not due to another health condition or to the unavailability of food. A commonly used threshold is body mass index (BMI) less than 18.5 kg/m2 in adults and BMI-for-age under 5th percentile in children and adolescents. Rapid weight loss (e.g. more than 20% of total body weight within 6 months) may replace the low body weight guideline as long as other diagnostic requirements are met. Children and adolescents may exhibit failure to gain weight as expected based on the individual developmental trajectory rather than weight loss. Low body weight is accompanied by a persistent pattern of behaviours to prevent restoration of normal weight, which may include behaviours aimed at reducing energy intake (restricted eating), purging behaviours (e.g. self-induced vomiting, misuse of laxatives), and behaviours aimed at incr

ICD-11 Criteria for Schizophrenia (6A20 )

ICD-11 Criteria for Schizophrenia (6A20 ) Schizophrenia is characterised by disturbances in multiple mental modalities, including thinking (e.g., delusions, disorganisation in the form of thought), perception (e.g., hallucinations), self-experience (e.g., the experience that one's feelings, impulses, thoughts, or behaviour are under the control of an external force), cognition (e.g., impaired attention, verbal memory, and social cognition), volition (e.g., loss of motivation), affect (e.g., blunted emotional expression), and behaviour (e.g., behaviour that appears bizarre or purposeless, unpredictable or inappropriate emotional responses that interfere with the organisation of behaviour). Psychomotor disturbances, including catatonia, may be present. Persistent delusions, persistent hallucinations, thought disorder, and experiences of influence, passivity, or control are considered core symptoms. Symptoms must have persisted for at least one month in order for a diagnosis of schi
