Are there other conditions that can mimic PD?
Essential Tremor (ET)
- Short for Essential Tremor, ET, is fairly common amongst the elderly population, yet may begin at any age.
- ET is different from the PD tremor in that it affects both hands, often involves head tremor and a shaky quality to the patient’s voice.
- Essential tremor is thought to be different from PD.
- However, recent research shows that ET may be a risk factor for PD. In fact, up to 20% of ET patients may develop Parkinsonian symptoms, Parkinson’s disease, or have a family member with PD.
Normal Pressure Hydrocephalus (NPH)
- A person with NPH has fluid inside the brain that does not drain properly, which results in difficulty in walking, slowed thinking, and loss of bladder control.
- NPH can usually be diagnosed by specialized brain scans, lumbar puncture (spinal tap), and a physical examination.
- The treatment often involves surgery where a shunt is placed to help drain the excess fluid.
