7. Sleep Disturbances: The Nighttime Struggles
Sleep disturbances, such as insomnia or rapid eye movement (REM) sleep behavior disorder, can also be early signs of Parkinson’s disease. Insomnia, or difficulty falling or staying asleep, can result from the motor symptoms of the condition, such as tremors or muscle stiffness, making it challenging to find a comfortable position for sleep. Additionally, individuals with Parkinson’s disease may experience excessive daytime sleepiness or frequent nighttime awakenings.
REM sleep behavior disorder, on the other hand, is characterized by vivid, often frightening dreams and physically acting out these dreams during sleep. Individuals with this disorder may kick, punch, or thrash about in their sleep, potentially causing injury to themselves or their bed partners. Studies have shown that a significant percentage of people with Parkinson’s disease experience REM sleep behavior disorder, and in some cases, this sleep disturbance can predate the onset of motor symptoms by several years.
As with other early warning signs, it’s important to recognize that sleep disturbances can have numerous causes. However, if you or a loved one is experiencing persistent sleep problems, particularly if accompanied by other early signs of Parkinson’s disease, it’s crucial to consult a healthcare professional for further evaluation and potential treatment options.
