First real experience of fatigue.. 

Fatigue is common in PD

Multiple studies in the United States and Europe show that about one-third of people with PD consider fatigue their single most bothersome symptom, even more than the motor symptoms of PD such as tremor, slowness, stiffness and difficulty with walking and balance. In addition, about one half of people rate fatigue as one of their three most bothersome symptoms.

Fatigue in PD tends to develop early in the disease, usually in the first few years, if it is going to develop at all. It may appear before the onset of motor symptoms, and typically does not go away. It is not correlated with the severity of other symptoms—a person with only mild motor symptoms may have significant fatigue, and a person with significant motor symptoms may experience little fatigue.
