Types of Dementia

Seven dementias, seven discriminators. The fast one with myoclonus. The triad where gait comes first. The stepwise decline with infarcts on imaging. The cluster of hallucinations and parkinsonism within a year. The timing rule that separates the two Lewy body diseases. The reversible one. And the default everyone else gets compared to. Plus the antipsychotic warning every clinician needs to know cold.
