Impaired movement and coordination, such as unsteady gait and loss of balance. Johnson” was a 67-year-old patient with Parkinson’s disease [1], a progressive, incurable disorder where dopamine level is decreased due to the death of the dopaminergic neurons in the substantia nigra and basal ganglia causing the patient to develop motor and non-motor symptoms. In addition to slow movements and reflexes, a person with bradykinesia may experience: immobile or frozen muscles. People with dystonia have involuntary muscle contractions that cause slow and repetitive movements. When this area of the brain is damaged, the individual may have. There are four basic types of eye movements: saccades, smooth pursuit movements, vergence movements, and vestibulo-ocular movements. A vertical gaze palsy (VGP) is a conjugate, bilateral, limitation of the eye movements in upgaze and/or downgaze. It can be unilateral or bilateral. Depending on which area of the brain is affected, there may also be problems with memory and other thought processes.
