A client is admitted to the emergency with Parkinson's disease. Which statement by the daughter would support the diagnosis?

• A. The patient repeats questions and asks where he placed his toothbrush.
• B. The patient has sudden severe headache.
• C. The patient cannot recognize family members.
• D. The patient experiences chest pain.

Answer: (A)

Parkinson's disease can involve cognitive changes as it progresses, not just motor symptoms. Repeating questions and misplacing familiar objects like a toothbrush reflect short-term memory impairment and mild confusion, which are nonmotor features seen with advancing PD or Parkinson's disease dementia. The other statements point to unrelated acute issues—sudden severe headache suggesting a possible intracranial event, inability to recognize family members indicating a more severe perceptual/dementia process, and chest pain hinting at a cardiac problem. Thus, the daughter's observation best supports the diagnosis by indicating cognitive decline associated with Parkinson's.
