Drinking small amounts of alcohol can relieve symptoms of essential tremor, although heavy drinking should be avoided. The majority of persons with PD remain alert and intelligent, but motor difficulties in facial expression and speech can give a false impression of cognitive im-pairment. LBD, which can occur in some patients with PD symptoms, is the second most com-mon form of dementia. It accounts for 15% to 20% of all dementias.
