Parkinson's disease: Causes and diagnosis What causes Parkinson’s disease? Parkinson's disease is caused by the progressive impairment or deterioration of neurons (nerve cells) in an area of the brain known as the substantia nigra. When functioning normally, these neurons produce a vital brain chemical known as dopamine. Dopamine serves as a chemical messenger allowing communication between the substantia nigra and another area of the brain called the corpus striatum. This communication coordinates smooth and balanced muscle movement.

What is Parkinson's disease? Parkinson s disease is a disorder of the Central Nervous System that affects the way the brain controls the body s movement. Dopamine is a chemical messenger inside your brain that transmits signals between nerve cells from different parts of the brain. In individuals with Parkinson s disease, the brain cells that create dopamine are not functioning, causing a lack of dopamine in the brain, thereby causing trouble with movement.

Parkinson's Disease Dementia The key brain changes linked to Parkinson's disease and Parkinson's disease dementia are abnormal microscopic deposits composed chiefly of alpha-synuclein, a protein that's found widely in the brain but whose normal function isn't yet known. The deposits are called Lewy bodies.

Parkinson Disease Parkinson disease (or, simply, Parkinson) is the most common form of Parkinsonism, a group of motor system disorders. It is a slowly progressing, degenerative disease caused by the loss of dopamine-producing brain cells. Dopamine is a substance made in the body that helps with smooth and coordinated muscle movement.

Parkinson Disease Nerve cells use a brain chemical called dopamine to help control muscle movement. With Parkinson disease, the brain cells that make dopamine slowly die. Without dopamine, the cells that control movement cannot send messages to the muscles. This makes it hard to control the muscles.

Non-Motor Symptoms of Parkinson's Disease The major problem in Parkinson’s disease (PD) is the gradual loss in the brain of the chemical messenger dopamine. Without this neurotransmitter brain cells that use dopamine cannot communicate with one another effectively. This communication breakdown leads to functional breakdowns in every brain system that uses dopamine.

Types of Parkinson's Disease Parkinson's Disease. Parkinson's disease is a brain disorder that occurs when neurons in the area of the brain called the substantia nigra begin to die. This interferes with the production of the chemical dopamine, which aids in muscle movement.Symptoms begin to appear when about 80 percent of the dopamine-producing cells are damaged.he main symptoms of Parkinson's include tremors, slow movements, stiffness and balance problems. While Parkinson's is not curable, there are medications that mimic dopamine and help with slowness, tremors and stiffness.

Parkinson's Disease  In-Depth Report Introduction. Parkinson's disease (PD) is a slowly progressive neurological disorder that affects movement, muscle control, and balance. Parkinson’s disease is part of a group of conditions called motor system disorders, which are associated with the loss of dopamine-producing brain cells.evodopa (L-dopa). Levodopa, or L-dopa, has been used for years and is the gold standard for treating Parkinson's disease. L-dopa increases brain levels of dopamine. It is probably the most effective drug for controlling symptoms and is used in nearly all phases of the disease.

Parkinsons Disease Parkinsons Disease. In a healthy brain, certain nerve cells produce the chemical dopamine. Dopamine transmits signals throughout the brain to coordinate smooth muscles movement. In Parkinson's patients, these dopamine-producing cells are damaged, dead, or have otherwise degenerated. This causes the nerve cells to fire erratically, leaving patients unable to control their movements.

Aging & Health A to Z Causes & Symptoms. Parkinson’s disease is caused by damage to a special kind of nerve cells (neurons) in a specific part of the brain that produce a chemical called dopamine. Dopamine sends messages throughout the body that help control movement. In people with Parkinson’s, these neurons produce less and less dopamine. As a result, controlling movement and carrying out other tasks gets increasingly difficult. The cause of the damage to these neurons is not known.
