ABSTRACT

The observation of dysfunctional behaviour is automatically reduced to a neurobiological simplification that reflects the prevailing dominance of the 'medical disease' model of dementia. Named after Alois Alzheimer, the German physician who first identified neurological disease of the cerebral cortex in 1907, this it is the most common form of dementia. Fronto-temporal dementia is dementia that is associated with cellular disease of the frontal and temporal lobes of the cerebral cortex. Vascular dementia, also known as multi-infarct dementia, follows a series of strokes, or infarcts, when a loss of blood flow damages specific areas of the brain. Subcortical dementia refers to the neuropsychological and behavioural symptoms of degenerative disorders involving, primarily, subcortical structures. In 1912 Frederic Lewy described lesions found in the brains of people suffering from Parkinson's disease. These became known as Lewy bodies. During the 1980s, a dementia was identified at post-mortem that was found to have Lewy bodies present in the cerebral cortex.
