Psychiatric Disorders, their cause and consequences
Learning disability and schizophernia and psychosis - what is this associated with?
change in personality and reduction in functional abilities
- self talk
Learning disability and mood disorders
Noted by change in behaviour ie biological symptoms - reduction in appetite, weight loss
Learning disability and anxiety disorders
- ritualistic behaviour and obsessional themes , work, day to day activities
- compulsions are more easily observed
half of those with LD have?
autism
Learning disability and Over-activity syndromes
ADHD much higher incidence
- look at developmental age
Many severe LD children are overactive, distractible and impulsive but NOT to extent that would indicate diagnosis of ADHD
Learning disability and challenging behaviour and self injury
usually as a result of stress or distress - aggression towards others wandering - destruction of property - PICA - sexually inappropriate
