<unk>  <unk>  is<unk>  that is associated with<unk> 's<unk>  (PD). Together with<unk>  with Lewy bodies (DLB), it is one of the Lewy body<unk> s characterized by abnormal deposits of Lewy bodies in the brain.<unk> 's<unk>  starts as a movement disorder, but progresses in most cases to include<unk> , and changes in mood and behavior. The signs, symptoms and cognitive profile of<unk>  are similar to those of DLB; DLB and<unk>  are clinically similar after<unk>  occurs in<unk> 's<unk> .<unk> 's<unk>  is a risk factor for<unk> ; it speeds up decline in cognition leading to<unk> . Up to 78% of people with PD have<unk> . Delusions in<unk>  are less common than in DLB, and persons with PD are typically less caught up in their visual hallucinations than those with DLB. There is a higher incidence of tremor at rest in PD than in DLB, and signs of<unk> ism in<unk>  are less symmetrical than in DLB.<unk>  can only be definitively diagnosed after death with an autopsy of the brain. The 2017 Fourth Consensus Report established diagnostic criteria for<unk>  and DLB. The diagnostic criteria are the same for both conditions, except that<unk>  is distinguished from DLB by the time frame in which<unk>  symptoms appear relative to<unk> ian symptoms. DLB is diagnosed when cognitive symptoms begin before or at the same time as<unk> ism.<unk>  is the diagnosis when<unk> 's<unk>  is well established before the<unk>  occurs; that is, the onset of<unk>  is more than a year after the onset of<unk> ian symptoms. Cognitive behavioral therapy can help<unk> 's patients with<unk> ian pain, insomnia, depression, anxiety, and impulse disorders, if those interventions are properly adapted to the motor, cognitive and executive dysfunctions seen in<unk> 's<unk> , including<unk> 's<unk> .
