About Cognitive Symptoms of Parkinson's Disease

Parkinson's disease (PD) is a disorder that mainly involves movement. According to the Parkinson's Disease Foundation (PDF), the brain cells that make the chemical dopamine do not function properly and the amount of dopamine they produce decreases. The lack of dopamine affects one's ability to move in a normal manner. Most people are aware that patients with PD often make uncontrollable movements, but other symptoms that may strike as well. Cognitive symptoms affecting organizational skills and basic thought processes may also result from PD.

Degrees of Cognitive Impairment

• The PDF reports that most PD patients experience some cognitive symptoms. Two terms associated with cognitive difficulties due to PD are "mild cognitive impairment" and, for more serious problems, "dementia."

Executive Dysfunction

• Executive dysfunction refers to the trouble some PD patients have with problem-solving, multi-tasking and planning. People who experience this type of cognitive impairment may feel overwhelmed at the prospect of completing a project or performing at a task.

Memory Problems

• Memory loss can occur as a result of PD, both in terms of recalling information and finding the correct words for items and concepts. The use of memory cues and repetition can help patients deal with this frustrating symptom.

Visual Dysfunction

• Some PD patients have trouble with their visual and spatial relations. This symptom can become dangerous in certain situations. For example, an affected person may make a mistake in calculating the location of the stairs, thus leading to a fall.

Treatment

• Treatment for cognitive symptoms of PD does not necessary make these symptoms disappear, but it can help people live as normally as possible. Occupational therapists often teach patients new ways of going about everyday activities.
