Parkinson's disease can be associated with dementia, especially in later stages of disease.  It is also possible that cognitive issues can be worsened by certain medications.  This is something that should be evaluated by a patient's primary care doctor or neurologist, especially since it may be necessary to slowly decrease a specific medication.  In addition, patients with dementia are often started on an anticholinergic medication to help some symptoms associated with dementia. 

Caring for an individual with dementia can be challenging, but it is important for family members to remain patient and supportive.  Sometimes it is helpful for people with dementia to keep physically active and mentally-stimulated as safety permits. Unfortunately, there is no cure for dementia at this time.
