A 60 year old man is brought to the physician by his wife, as she has noticed changes in his personality over the past 18 months. From a pleasant, cheerful person he has become very irritable. A few months later he has become aphasic. He has no motor or sensory deficits, no tremors or gait disturbances. MRI shows marked temporal and frontal gyral atrophy. His frontal cortex shows extensive neuronal damage, some neurons showing intracytoplasmic faintly eosinophilic round inclusion bodies which stain positive for tau protein.

Parkinson’s disease
-
Vascular dementia
-
Huntingtons disease
