Corticobasal degeneration (CBD) is a rare type of Parkinsonism that affects people from the age of 40, typically between the ages of 50 to 70. It tends to affect one side of the body more than the other initially, gradually spreading over the course of a few years.
Drug-induced Parkinsonism usually presents itself symmetrically. Freezing, which is more common in Parkinson’s disease, is a rare occurrence in drug-induced Parkinsonism. Incidence of rest tremor is more evident in drug-induced Parkinsonism than in Parkinson’s disease. Studies have also known that drug-induced Parkinsonism is more common in females, whereas Parkinson’s disease is more common in males.
Essential tremor doesn't cause other health problems, but Parkinson's disease is associated with stooped posture, slow movement and shuffling gait. However, people with essential tremor sometimes develop other neurological signs and symptoms, such as an unsteady gait (ataxia).
Rigidity also can occur in the hips and ankles, and in the neck and trunk (rigidity in your neck and trunk is called "axial rigidity"). Unlike some neurological conditions which affect muscle tone, the rigidity in Parkinson's disease affects flexor and extensor muscles equally.
Bradykinesia, which means slow movement, is one of the characteristic motor symptoms of PD. Bradykinesia is noticeable as the gradual loss and slowing down of spontaneous movement, which may appear as a decrease in facial expressions and a chronic, abnormal stillness.
Both can be helped by seeing a speech pathologist or speech therapist. In particular, the Lee Silverman Voice Therapy Program, has demonstrated significant value for people with Parkinson's. Ask your doctor about a referral to a speech pathologist experienced in administering the Lee Silverman Voice Therapy program.
Parkinson’s disease is typically divided into five stages. Learn more about each stage and associated symptoms. The main symptoms of Parkinson’s disease include uncontrollable shaking and tremors, slowed movement (bradykinesia), and stiffness in your limbs.
Parkinson’s is a progressive disorder, which means your symptoms get more serious over time. It can affect your movements as well as things like your vision, sleep, and mental health. A person with Parkinson’s can get different symptoms at different times than someone else with the same condition.
Vascular (Arteriosclerotic) parkinsonism can be difficult to distinguish from Parkinson’s. However, stroke symptoms tend to appear suddenly and do not progress, whereas the symptoms of Parkinson’s appear gradually and get worse over time. Vascular parkinsonism usually affects the legs more than the upper part of the body.
