Dr. Dolhun explains that cognitive dysfunction is a non-motor symptom whereby a person’s memory or thinking ability is compromised. It can happen at any point in Parkinson’s disease and the severity can vary from patient to patient. She then talks about the brain cell changes that occur in Parkinson’s disease patients and how cognitive dysfunction can lead to dementia.

    After two 1 1/2 hour sessions weekly of Rock Steady Boxing here in Juneau, Alaska, I’m down to 1 to 1 1/2 hours of sleep per night. I don’t know if at age 75+ I’m not coping well with my fight or flight response (cortisol/adrenaline) or I’m simply so “out of shape” that I can’t cope. I was a physical education teacher and have prided myself on my physical appearance and condition for years. What are your thoughts?
