A severe brain injury produces physiological, cognitive, emotional, psychological and behavioural changes. Some individuals develop medical problems related to specific deficits caused by the brain injury. The part of the brain that is injured determines the long-term effects. Often a severe brain injury involves multiple areas of the brain, resulting in multiple disabilities. Physical functions can be affected, such as standing, walking and eye-hand coordination. Cognitive changes can include issues with memory and language. Personality traits can be affected. People may lose their natural inhibitions and behaviour control, leading to inappropriate behaviour. The effects of a brain injury can be extremely widespread, impacting all areas of a person’s life and requiring extensive medical and rehabilitative treatment.
In cases of severe brain injury it is an open question as to how well the ‘higher mental functions’ (cognitive: ie. memory, concentration, reading, planning, etc) will ever fullyrecover (even over some time), yet with a strong will and determination they CAN be managed adequately through adapting to any deficiences.
