Causes Of Pseudobulbar Affect

Parkinson's Disease

One survey of Parkinson's disease patients indicated that of the 449 surveyed, about 3.6 percent showed symptoms of pseudobulbar affect. If this statistic is applied to all Parkinson's disease patients across the United States, there may be thirty-five thousand who have pseudobulbar affect. Other sources believe the rate of pseudobulbar affect among Parkinson's disease patients might be closer to twenty-four percent, meaning almost one in four Parkinson's disease patients have symptoms of pseudobulbar affect. Experts believe the condition is often undiagnosed because patients aren't aware of it. Parkinson's disease is a progressive disorder of the nervous system that mainly affects movement. Symptoms might begin with tremors, although the disease can also cause slowing and stiffness. There isn't any cure for Parkinson's disease. The disease happens when the brain's nerve cells begin to break down and die. When the patient's brain loses the ability to produce dopamine, the decrease in dopamine leads to abnormal activity in the brain.
