Cognitive Concerns in Parkinson’s Disease: Early Signs, Risk Factors, and What Caregivers Should Know (Part 2)
In Part 2 of this educational series, the focus shifts from understanding cognitive changes in Parkinson’s disease to actively managing them. As the disease progresses, cognitive and behavioral symptoms require a thoughtful, proactive approach that supports both the individual and the caregiver. Part 2 of this session, presented by Catherine McDermott, APRN, PMHNP-BC, focuses on helping caregivers and families better understand the cognitive side of Parkinson’s disease. Catherine is a double board-certified Psychiatric Mental Health Nurse Practitioner specializing in geriatric psychiatry, cognitive impairment, and dementia care. With over 30 years of experience, she brings both clinical expertise and a compassionate, practical approach to supporting families navigating complex diagnoses.
One of the most critical areas addressed is mental health. Advocacy for psychiatric care is essential, particularly for this generation, where stigma often prevents individuals from seeking support. Depression in Parkinson’s disease is not simply emotional. It is a neurological condition driven by changes in neurotransmitters such as dopamine, serotonin, and epinephrine. When these imbalances are properly treated, individuals often experience meaningful improvements not only in mood but also in cognitive function and overall quality of life.
Ongoing and periodic evaluation plays a central role in care. Cognitive changes can be subtle and gradual, making them easy to overlook without a structured assessment. A comprehensive, interdisciplinary approach that includes neurology, neuropsychology, and psychiatric support allows for more accurate identification of changes and more effective, individualized treatment planning.
Medication management is another cornerstone of care and one of the most common areas where challenges arise. As executive function declines, managing multiple medications becomes increasingly complex. Individuals may forget doses, take incorrect amounts, or struggle to follow schedules. This type of mismanagement is one of the leading causes of hospitalization in individuals with Parkinson’s disease, making regular medication reviews and simplification strategies essential.
As cognitive impairment progresses, safety concerns become more prominent. One of the most sensitive and difficult topics for families is driving. Reduced awareness, slowed processing, and impaired decision-making can significantly increase risk. These situations often require honest, proactive conversations that prioritize safety while acknowledging the emotional impact of losing independence.
At the same time, caregiver burden continues to grow. Supporting someone with both motor and cognitive decline can be physically demanding and emotionally exhausting. Caregivers often face increased stress, burnout, and decision fatigue. This makes access to support systems, education, and respite care not just helpful but necessary for long-term sustainability.
Management strategies for cognitive concerns in Parkinson’s disease extend beyond medication alone. Addressing mood disorders remains a priority, as untreated depression and anxiety can worsen cognitive symptoms. In addition, optimizing daily routines and incorporating lifestyle modifications can have a meaningful impact. Consistent sleep patterns, adequate sunlight exposure, proper nutrition, and structured daily routines all support brain health and overall functioning.
Non-pharmacological interventions are equally important. Evidence-based cognitive programming, which actively engages in multiple areas of the brain, has been shown to be more effective than passive activities. Purposeful engagement, social interaction, and structured cognitive exercises can help maintain function and improve quality of life.
While research in Parkinson’s disease continues to advance, particularly in the area of biomarkers and early detection, there are still significant gaps. Early identification of cognitive decline remains a challenge, reinforcing the importance of education, awareness, and proactive care.
The key takeaway from this session is that cognitive decline in Parkinson’s disease is progressive, but not without opportunity for intervention. Early recognition, consistent evaluation, interdisciplinary collaboration, and individualized care strategies can significantly improve outcomes and help individuals maintain independence and quality of life for as long as possible.
The session also highlights important real-world considerations raised during discussion, including the importance of psychiatric support, the challenges families face navigating insurance for specialized care, and the role of physical activity in supporting brain health through increased blood flow. Additionally, it reinforces the value of community-based resources, such as those offered through Town Square University Parkway, where education, support, and engagement are integrated into care.
Ultimately, managing cognitive concerns in Parkinson’s disease requires a comprehensive and compassionate approach. With the right tools, support systems, and education, both individuals and caregivers can navigate this journey with greater confidence and stability.
