D571 Task 2 DSM-5 Disorders
Neurodevelopmental Intellectual Disability (ID)
Major deficits in cognitive functioning and adaptive
functioning. Three sets of criteria are used.
Criteria A:
• Trouble with thinking skills (Problem solving,
Learning, Judgement, Abstract Thinking).
• Confirmed by tests and Assessments.
Criteria B:
• Difficulty with Daily Life (Communication,
DSM-5 Criteria Independence, Social Skills).
• Struggle across different places like home,
school, work.
Criteria C:
• Problems start during childhood developmental
period.
(American Psychiatric Association, 2022)
Genetics: Genetic conditions like Down Syndrome
could cause abnormalities in brain structure and
function. This leads to issues with learning and
problem solving.
Biopsychosocial Factors Environmental: Environmental factors such as
maternal malnutrition, or exposure to drugs can cause
damage delayed mental development, or congenital
disorders.
(Miller, n.d.)
, Community Supports and Programs-Assist with

Psychotic Schizophrenia
Having at least two of these symptoms (One of the
three must be either delusions, hallucinations or
disorganized speech).

of the time for a month. Also causes significant issues
in daily life for at least six months.
DSM-5 Criteria • Delusions
• Hallucinations
• Disorganized
• Catatonic Behavior, grossly
disorganized/abnormal behavior

(American Psychiatric Association, 2022)
Genetics: Twin and family studies consistently
support a genetic basis for schizophrenia. If one
identical twin develops schizophrenia, there is a 48%
chance the other will also develop the disorder; family
studies have also found similarities in brain
abnormalities among individuals with schizophrenia
and their relatives (Bridley & Daffin, 2024).
Biopsychosocial Factors
Psychological: Neurocognitive impairments lead to
adverse experiences, fostering dysfunctional beliefs
and behaviors like delusions and hallucinations.
