acquired brain injury
Acquired Brain Injury is the “multiple disabilities arising from damage to the brain acquired after birth. It results in deterioration in cognitive, physical, emotional or independent functioning. It can be as a result of accidents, stroke, brain tumours, infection, poisoning, lack of oxygen, degenerative neurological disease etc.” (The National Community Services Data Dictionary (Australian Institute of Health and Welfare, Canberra, 2012)

Loss of motivation, difficulty with initiating activities, gives the appearance of lethargy.

Inability to recognise familiar objects or sounds, although functioning of the sense organs and intelligence are normal.

Complete or partial loss of the sense of smell.

anterograde amnesia
