(Sleep Deprivation Caused Memory Defects and Emotional Changes in a Rotenone-based Zebra fish Model of Parkinson’s Disease”, published in Behavioural Brain Research.)
Researchers wrote: “In addition to cognitive and emotional disorders, sleep abnormalities are also prevalent in Parkinson’s disease. The problem of sleep is not only the characteristics of the disease itself, but also related to medication and dyskinesia such as tremor and rigidity.”
