ConditionsParkinson’s Disease

Parkinson’s Disease (PD) is a degenerative condition affecting the brain causing a loss of a brain chemical called dopamine manifesting as tremor at rest, slowing down of movements (bradykinesia), stiffness of the limbs (rigidity), and a range of non-motor symptoms.

The part of the brain that is affected is called the basal ganglia, which functions like the autopilot of your brain, facilitating subconscious (automatic) movements. Because PD causes the brain cells in this deep circuitry to deteriorate, patients’ natural movements become slow and stiff. Many patients describe feeling as if they had aged overnight.

Everyday tasks such as getting dressed, writing, picking something up off the floor take twice as long as they used to. Some people describe the feeling of slowness and stiffness as walking through molasses or moving in slow-motion. Because subconscious muscle movements of the face are responsible for one’s facial expressions and others’ interpretation of our mood, patients can be thought to be upset or depressed when they are not. This is known as having a masked face.

The voice is affected too, because the voice box is ultimately controlled by the basal ganglia as well. Thus the voice becomes soft, slurred and hushed. Others may comment that the patient is mumbling. The mumbling goes away temporarily once the patient becomes aware of it but soon returns to the soft, slurred state. This temporary improvement when attention is paid is true of many of the motor symptoms of PD because the condition primarily affects subconscious movements, and does not directly affect nerve or muscle control at the most basic level. Thus, conscious awareness can override the slowness to a certain extent. This fact is one reason why physical therapy and physical activity are so useful and necessary in treating PD.

At the Pacific Movement Disorders Center, we provide a personally tailored approach to the management of PD including the use of the newest FDA-approved medications and the use of deep brain stimulation (DBS) when appropriate.

Conditions that may mimic Parkinson’s disease
Deep Brain Stimulation (DBS)
Medications for Parkinson’s Disease

  • Lightheadedness from blood pressure dropping upon standing
  • Urinary difficulties such as increased frequency, increased urgency, trouble making it to the bathroom on time (incontinence)
  • Anxiety
  • Depression
  • Fatigue
  • Cognitive difficulties including dementia
  • Hallucinations
  • Sleep disturbances, vivid dreams, acting out dreams, REM sleep behavior disorder (RBD)
  • Gastrointestinal changes such as constipation, delayed stomach emptying, loss of sense of smell or taste (may precede symptoms by many years)

PD is a “clinical diagnosis,” meaning that it is based on the patient’s exam and history. There is no blood test for PD. MRI is sometimes done to exclude other conditions that can mimic PD, but is not necessary if the clinical signs are consistent with the disease. Our clinics offer DaTscan, a new functional imaging technique which accurately distinguishes between Parkinson’s tremor and other causes of tremor.

Medical non-surgical treatment

  • Exercise: The best form of treatment is exercise, exercise, exercise! Depending on the patient, this may mean physical therapy, participation in PD-specific exercise classes, working with a personal trainer, use of fitness videos, or independent exercise. The idea is to tailor the medical and surgical treatment to maximize the ability of the patient to exercise. Speech therapy can also be helpful for slow, soft, or slurred speech.

Surgical treatment

This is advised when the disease progresses and the medications are no longer controlling the symptoms of PD adequately.

  • As the disease progresses, Levodopa still works, but the brain’s response to the medication becomes less predictable. Levodopa may take longer to kick in and may wear off earlier, requiring patients to take medication more frequently during the day. Higher doses of levodopa are associated with abnormal involuntary movements, known as dyskinesias (this does not include tremor). Unpredictable medication effect results in “OFF” time when patients feel stiff, rigid, stuck, frozen, slow, or fatigued, compared to “ON” time when movements are smooth and closer to normal.
  • Treatment options as the disease progresses include taking levodopa more frequently; making the medication last longer by adding medications to reduce the metabolism of levodopa, or dopamine (Comtan, Azilect) adding or changing to long-acting forms of levodopa (Sinemet CR, Rytary), or adding or changing to long-acting forms of dopamine agonist (Neupro patch). Amantadine can be added to reduce dyskinesia. As these options are being considered and implemented, it’s time to consider deep brain stimulation surgery (DBS).
  • Deep brain stimulation surgery is FDA-approved for the treatment of motor complications in Parkinson’s disease and is not experimental. DBS is not a last-resort treatment. It has been shown that DBS is more beneficial when performed earlier in the course of the disease compared to waiting for disability.
