Q

9 common causes of haemorrhage..

A
  1. Hypertension damage to blood vessels (50%)
  2. Cerebral amyloid angiopathy - build up of plaques in walls of arteries (10%)
  3. Excessive cerebral blood flow
  4. Aneurysm rupture (vessels can expand and restrict also may have a ballon due to this if the wall is weakened, can rupture completed)
  5. Arteriovenous malformations eg weak walls
  6. Tumour
  7. Infection
  8. Trauma
  9. Obstruction to veins leaving the brain

Q

Risk factors include ( anything that damages or interferes with blood supply)

A

Hypertension
Hypercholesterolemia - fatty deposits reduce elasticity making ruptures more likely, embolism less likely to pass through…
Obesity - more vessels heart working harder
Smoking -hardening vessels
Alcohol - neurotoxin
Sodium intake

A

Poses distress to survivor and their system.
Can be an obstacle to rehabilitation.
Psychoeducation can reduce distress and prevent relationship breakdown.

Small dose antidepressants can help as it is a psychomotor problem.

35
Q

Greatest natural recovery occurs during…

A

The first month

36
Q

Natural functional recovery includes:
