5. Parkinson’s disease
Anhedonia occurs frequently in people who are affected by Parkinson’s disease, with rates between 7%–45% being reported in studies. Whether or not anhedonia is directly related to the high rates of depression in Parkinson’s disease is unknown, but the correlation does little to rule this out.
Some of the misconceptions about Parkinson’s disease see it labeled as something which only affects the old and the weak, but this is untrue, as Parkinson’s can affect young people too.
As this is the case, the risk that Parkinson’s poses for people in terms of the developing conditions such as anhedonia is significant and must be considered, as the earlier someone is diagnosed with Parkinson’s disease, the more of their life they have left to live and the greater the potential for them to experience less enjoyment from all areas of their life.
The prevalence of depression in Parkinson’s sufferers is also something that must play a part in this.
