Cold temperatures are known to increase tremor severity in Parkinson's disease patients, likely due to temperature sensitivity affecting basal ganglia motor control. This seasonal effect is a recognized clinical observation that patients and caregivers should monitor and manage accordingly.
Recent observational studies suggest the Mediterranean diet may be associated with reduced cognitive decline and lower Alzheimer's disease risk, possibly through vascular, metabolic, and anti-inflammatory mechanisms.

The article reviews current evidence on cognitive decline prevention, screening, diagnosis, treatment options, and quality of life considerations for both patients and caregivers.
