Cholinesterase Inhibitors

A group of drugs that prevent acetylcholine breakdown in the synaptic cleft by acetylcholinesterase and increase its uptake in the postsynaptic receptor. The most common of these drugs are donepezil, rivastigmine and galantamine.


An impact to the head which jars the brain and temporarily disrupts its normal functioning.

Closed Head Injury

A concussion or head trauma, the symptoms of which include loss of consciousness after the trauma, confusion, headache, nausea or vomiting, blurred vision, loss of short-term memory and perseverating.

Deep Brain Stimulation (DBS)

A form of treatment for Parkinson’s disease which uses a surgically implanted, battery-operated device called a neurostimulator to deliver electrical stimulation to the ventral intermediate nucleus of the thalamus or the subthalamic nucleus area in the basal ganglia.


A disturbance of consciousness that develops over a short period of time.

Cerebral Thrombosis

An injury caused when a blood clot (thrombus) forms in an artery (blood vessel) supplying blood to the brain. The clot interrupts the blood supply and brain cells are starved of oxygen.

Constraint-Induced Movement Therapy (CIMT)

A technique used with aphasic patients which involves the mass practice of verbal responses in which the patient may be required to communicate without gesturing or pointing to describe various objects of varying complexity.


A severe head trauma in which the brain is not just jarred but the impact also causes bruising to the brain.
