Dementia associated with Alcoholisim
F10.7 Residual And Late-Onset Psychotic Disorder
A disorder in which alcohol- or psychoactive substance-induced
changes of cognition, affect, personality, or behaviour persist
beyond the period during which a direct psychoactive
substance-related effect might reasonably be assumed to be
Onset of the disorder should be directly related to the use of
alcohol or a psychoactive substance. Cases in which initial onset
occurs later than episode(s) of substance use should be coded here
only where clear and strong evidence is available to attribute the
state to the residual effect of the substance. The disorder should
represent a change from or marked exaggeration of prior and normal
state of functioning.
The disorder should persist beyond any period of time during
which direct effects of the psychoactive substance might be
assumed to be operative (see F1x.0, acute intoxication). Alcohol-
or psychoactive substance-induced dementia is not always
irreversible; after an extended period of total abstinence,
intellectual functions and memory may improve.
The disorder should be carefully distinguished from
withdrawal-related conditions (see F1x.3 and F1x.4). It should be
remembered that, under certain conditions and for certain
substances, withdrawal state phenomena may be present for a period
of many days or weeks after discontinuation of the substance.
Conditions induced by a psychoactive substance, persisting
after its use, and meeting the criteria for diagnosis of psychotic
disorder should not be diagnosed here (use F1x.5, psychotic
disorder). Patients who show the chronic end-state of Korsakov's
syndrome should be coded under F1x.6.
Consider: pre-existing mental disorder masked by substance use and
re-emerging as psychoactive substance-related effects fade (for
example, phobic anxiety, a depressive disorder, schizophrenia, or
schizotypal disorder). In the case of flashbacks, consider acute
and transient psychotic disorders (F23.-). Consider also organic
injury and mild or moderate mental retardation (F70-F71), which
may coexist with psychoactive substance misuse.
This diagnostic rubric may be further subdivided by using the
following five-character codes:
May be distinguished from psychotic disorders partly by their
episodic nature, frequently of very short duration (seconds or
minutes) and by their duplication (sometimes exact) of previous
F1x.71 Personality or behaviour disorder
Meeting the criteria for organic personality disorder (F07.0).
F1x.72 Residual affective disorder
Meeting the criteria for organic mood [affective] disorders
Meeting the general criteria for dementia as outlined in the
introduction to F00-F09.
F1x.74 Other persisting cognitive impairment
A residual category for disorders with persisting cognitive
impairment, which do not meet the criteria for psychoactive
substance-induced amnesic syndrome (F1x.6) or dementia (F1x.73).
