Sudden and involuntary muscle spasms of the head, neck, lips, tongue, and eyes are characteristic symptoms of dystonia. Slurred speech is also a possible symptom of this neurological disorder. Akathesia refers to a state of inner restlessness, while tardive dyskinesia is characterized by involuntary repetitive movements of the face and limbs, usually caused by long-term use of medications that block dopamine receptors. Parkinsonism is a set of symptoms that include tremors, rigidity, bradykinesia, and postural instability, usually associated with Parkinson's disease. While dystonia can be a symptom of Parkinson's disease, the sudden onset of spasms and slurred speech are more suggestive of a dystonic reaction to certain medications or other underlying conditions.
