<unk>  is characterized by repetitive, involuntary movements. Some examples of these types of involuntary movements include: * Grimacing * Tongue movements * Lip smacking * Lip puckering * Pursing of the lips * Excessive eye blinking * Rapid, involuntary movements of the limbs, torso, and fingers may also occur. In some cases, an individual's legs can be so affected that walking becomes difficult or impossible. These symptoms are the opposite of people who are diagnosed with Parkinson's disease. People with Parkinson's have difficulty moving, whereas people with<unk>  have difficulty not moving. Respiratory irregularity, such as grunting and difficulty breathing, is another symptom associated with<unk> , although studies have shown that the rate of people affected is relatively low.<unk>  is often misdiagnosed as a mental illness rather than a neurological disorder, and as a result, people are prescribed neuroleptic drugs, which increase the probability that the person will develop a severe and disabling case, and shortening the typical survival period. Other closely related neurological disorders have been recognized as variants of<unk> .<unk>  dystonia is similar to standard dystonia but permanent.<unk>  akathisia involves painful feelings of inner tension and anxiety and a compulsive drive to move the body. In some extreme cases, afflicted individuals experience so much internal tension that they lose their ability to sit still.<unk>  tourettism is a tic disorder featuring the same symptoms as Tourette syndrome. The two disorders are extremely close in nature and often can only be differentiated by the details of their respective onsets.<unk>  myoclonus, a rare disorder, presents as brief jerks of muscles in the face, neck, trunk, and extremities. "AIMS Examination": This test is used when psychotropic medications have been prescribed because people sometimes develop<unk>  due to prolonged use of antipsychotic medications. The Abnormal Involuntary Movement Scale (AIMS) examination is a test used to identify the symptoms of<unk>  <unk> . The test is not meant to tell whether there is an absence or presence of<unk> . It just scales to the level of symptoms indicated by the actions observed. The levels range from none to severe. The AIMS examination was constructed in the 1970s to measure involuntary facial, trunk, and limb movements. It is best to do this test before and after the administration of the psychotropic drugs. Taking the AIMS consistently can help to track severity of<unk>  over time.
