Several diseases can mimic Parkinson’s disease symptoms, making diagnosis challenging. These include Lewy Body Dementia, Multiple System Atrophy, Progressive Supranuclear Palsy, and Corticobasal Degeneration. Additionally, essential tremor and dystonia can overlap with Parkinson’s.
Here’s a more detailed look at these conditions:
Here’s a more detailed look at these conditions:
Lewy Body Dementia (LBD):
LBD shares the motor symptoms of Parkinson’s but also includes dementia, affecting memory and thinking.
Multiple System Atrophy (MSA):
MSA, like Parkinson’s, is a progressive neurodegenerative disorder, but it also affects other parts of the nervous system, leading to symptoms like incoordination and autonomic dysfunction.
Progressive Supranuclear Palsy (PSP):
PSP often mimics Parkinson’s, but progresses more rapidly. A hallmark of PSP is difficulty moving the eyes up and down.
Corticobasal Degeneration (CBD):
CBD primarily affects movement, speech, and thinking. It can also cause abnormal limb posturing and the sensation of a limb “having a mind of its own”.
Essential Tremor (ET):
ET causes rhythmic shaking in the hands, head, voice, or legs, and can be confused with Parkinson’s.
Dystonia:
Dystonia involves muscle spasms and contractions, and while not directly a Parkinson’s disease mimic, it can be a complication of Parkinson’s or occur alongside it.
