what is the difference between delirium &dementia?

Answer 1

Delirium and dementia, both debilitating diseases most commonly in the elderly, are easily confused, but there are notable differences. The most prominent, or widely known, is the mode of onset. Onset of delirium is acute or subacute while onset of dementia is chronic or subacute.
In delirium, there are prominent motor signs like postural tremor, twitching in certain muscle groups (myoclonus), etc which are not usually seen in dementia -- unless vary late stages.
The key differentiation lies in the itme of onset of signs and symptoms - most of the signs and symptoms occur earlier in delirium, like speech defects, memory impairment, disorganised thought and behaviour, etc while they occur later in dementia.
The causes are different, dementia even thought it occurs later, is practically irreversible.
