Parkinson’s disease: What to look for

Alicia Colombo

In observation of Parkinson’s Awareness Month in April, Milestones recognizes the opportunity to increase awareness of the ailment and its symptoms. Parkinson’s disease (PD) is a long-term brain disorder where the central nervous system degenerates, affecting the body’s motor functions. About 10-15% of people with Parkinson’s disease have a family history of the condition.

Motor symptoms
According to the American Parkinson Disease Association, there are four primary motor symptoms of PD:

  • Tremors, or trembling, of the hands, arms, legs, jaw or head.
  • Rigidity, or stiffness, of the limbs and trunk.
  • Slowness of movement, referred to as “bradykinesia.”
  • Impaired balance and coordination, called “postural instability.”

Observing two or more of these symptoms is the main way that physicians diagnose PD. It is important to know that not all these symptoms need be present for a diagnosis to be made.

Non-motor symptoms
Because PD is a movement disorder, the associated non-motor symptoms can often be overlooked. Common symptoms of Parkinson’s that do not primarily involve movement include:

  • Depression and other emotional changes.
  • Difficulty swallowing, chewing and speaking.
  • Urinary problems or constipation.
  • Skin problems, including increased or decreased sweating; patches of scaly, irritated skin and dandruff (known as seborrheic dermatitis); and skin cancer.
  • Sleep disruptions.

Disease progression
According to the National Institute on Aging, early symptoms of PD are subtle and usually begin gradually but worsen over time. Many people with PD notice sleep problems, constipation, decreased ability to smell and restless legs, prior to experiencing stiffness and tremors. One side of the body is often affected first. As the disease progresses, the entire body becomes affected.

Friends or family members may be the first to notice changes in someone with PD, such as a lack of facial expression or an arm that does not move normally.

Sometimes, people dismiss early symptoms of PD as effects of normal aging. In most cases, there are no medical tests to definitively detect the disease, so it can be difficult to diagnose accurately. If you suspect that you or someone you know may have Parkinson’s disease, see a neurologist or movement disorders specialist.
