15 Lesser-Known Signs That May Point to Parkinson’s Disease

13. Excessive Sweating or Seborrheic Dermatitis

Excessive sweating and seborrheic dermatitis are lesser-known symptoms of Parkinson’s disease. The condition’s impact on the autonomic nervous system can lead to episodes of unexplained, excessive sweating, particularly on the hands, feet, or face. This can occur even in cool environments or during minimal physical exertion. In addition, many patients develop seborrheic dermatitis, characterized by oily skin, redness, and flaky patches, most commonly on the scalp, face, or upper chest. These skin changes result from increased activity of the sebaceous (oil) glands, likely linked to altered dopamine signaling. Both symptoms can cause discomfort, self-consciousness, and a diminished quality of life. Management strategies include using antiperspirants, medicated shampoos, or topical treatments for seborrheic dermatitis. Dermatologists and neurologists can collaborate to address these symptoms effectively. Recognizing and treating these skin-related issues can significantly improve comfort and confidence for individuals living with Parkinson’s disease.

14. Urinary Problems

Urinary issues are a frequently overlooked symptom of Parkinson’s disease. They stem from the condition’s impact on the autonomic nervous system, which controls involuntary bodily functions. Common urinary problems include increased urgency, frequency, or difficulty starting urination. Some patients may also experience nocturia (frequent nighttime urination), which disrupts sleep and contributes to fatigue. These symptoms occur because Parkinson’s affects the nerve pathways responsible for bladder control, leading to overactive or poorly coordinated bladder muscles. While these issues may initially seem unrelated to Parkinson’s, they can significantly impact daily life, leading to discomfort and reduced confidence. Management options include pelvic floor exercises, medications to relax the bladder, and lifestyle modifications, such as fluid management. Consulting with a urologist or a specialist in autonomic disorders can help tailor treatment to the individual’s needs. Addressing urinary problems early can enhance comfort and independence for those with Parkinson’s disease.
