1. Eye Movement Abnormalities
One of the lesser-known signs of Tardive Dyskinesia is abnormal eye movements. Patients with TD may experience rapid blinking, involuntary eye closure, or difficulty in controlling their eye movements. These eye movement abnormalities can significantly affect vision and overall quality of life.
2. Speech and Swallowing Difficulties
Tardive Dyskinesia can also manifest as speech and swallowing difficulties. Patients may experience slurred speech, rapid or irregular speech patterns, or difficulty in articulating words. Swallowing difficulties, known as dysphagia, can also be a symptom of TD and can lead to choking or aspiration.
3. Finger Movements and Hand Tremors
In some cases, Tardive Dyskinesia can affect finger movements and result in involuntary finger twitching, tapping, or wriggling. Hand tremors, characterized by uncontrollable shaking of the hands, can also be observed in individuals with TD. These motor abnormalities can interfere with fine motor skills and daily activities.
4. Trunk and Limb Movements
Tardive Dyskinesia can involve trunk and limb movements that are out of the individual's control. Patients may experience twisting or jerking movements of the torso, hips, or limbs. These abnormal movements can be disruptive and affect mobility and coordination.
