bio-psycho-social model
systemic approach (focus on relationships and social context e.g., school,m fmaily)
4 Ps formulation:
o Predisposing factors
o Precipitating factors
o Perpetuating factors
o Protective factors
When does half of all mental health conditions start by?
Half of all mental health conditions start by 14 years of age but most cases are undetected and untreated
What are the stages of development measured by?
erikson’s stages of psychosocial development
What is the adlescent brain like?
- The prefrontal cortex matures later than the cortical areas associated with sensory and motor tasks
- Adolescence is a period of neural imbalance caused by early maturation of subcortical brain areas and delayed maturation of prefrontal control areas
What are the stages of development according to erikson’s stages?
dont need to know its a visual
What is the peak age of onset for attention deficit hyperactivity disorder, autism spectrum disorder, eating disorders?
ADHD= 12
ASD= 9
eating= 17
What are the core features of diagnosis for ADHD according to DSM-5 criteria?
- Persistent pattern of inattention and/or hyperactivity-impulsivity
- Present for at least 6 months
- Inappropriate for their developmental level
- Interferes with functioning or development
- Several symptoms present before age 12
- Several symptoms present in two or more settings
- The symptoms are not better explained by another mental disorder
What are the risk factors of ADHD?
Genetic Risk Factors:
* No isolated gene for ADHD, there are likely multiple genes conferring vulnerability for developing it
* Twin studies have shown a significant heritability for ADHD - as high as 76%
* First degree relatives of children with ADHD have an ADHD diagnostic probability 4-5x higher than the
general population
* Boys are more vulnerable than girls
Environmental Risk Factors:
* Premature birth
* Low birth weight
* Prenatal smoking exposure
What are the subtypes for ADHD?
inattentive
hyperactive
combined
What is the prognosis of ADHD?
70% of children who have this disorder will have the disorder as teenagers, and about 40%- 60% will still have it as adults
- its not that it goes away, it is just easier to manage
What is dementia?
Degenerative disease of the brain:
o Irreversible and progressive changes
o Global cognitive and behavioural impairment
o Sufficiently severe to interfere significantly with
social and occupational function
o An umbrella term that has many underlying
causes
o Can be conceptualised as “chronic brain failure”
What are the reversible causes of dementia?
Reversible causes (not exhaustive)…
* Normal pressure hydrocephalus
* Intracranial tumours
* Subdural haematoma
* Depression
* B1, B6, B12 deficiency
* Folate deficiency
* Hypothyroidism
* Neurosyphilis
* Delirium
- Always think to exclude – Surgical, metabolic, infective and psychiatric reversible causes for cognitive impairment
What are causes dementia?
frontotemporal dementia
parkinson’s dementia
dementia with lewy bodies
mixed
vascular dementia
alzheimer’s disease
What is this and what caused it? What does it clinically present with?
Example of normal pressure hydrocephalus. Note the dilated ventricles.
Clinically presents with the Hakim-Adams triad;
- Cognitive impairment/confusion
- Urinary frequency/incontinence
- Gait disturbance (magnetic/stuck to the floor gait)
How does dementia cause death?
e.g., stops eating, loss of basic drive, can stop swallowing (aspiration leads to sepsis)
