Mild to Severe Signs of Tardive Dyskinesia You Should Pay Attention To

Mild Signs
Facial and oral movements are the most common presenting signs. Early signs of Tardive Dyskinesia include subtle movements of the surface or body of the tongue, increased eye blinking, and jerking of the fingers or toes. There may be involuntary movements of the forehead, eyebrows, periorbital area, and cheeks, as well as involuntary frowning, blinking, smiling, and grimacing.

Also typical are involuntary puckering, pouting, and smacking of the lips. Involuntary biting, clenching, chewing, mouth opening, and lateral movements of the jaw may also occur, along with protrusion, tremor, and choreoathetoid movements (ie, rolling, worm-like movement of the tongue without displacement from the mouth).

Moderate Signs
Movements of the arms, wrists, hands, and fingers in a repetitive or rapid manner will occur in its moderate form. Occasional involuntary movements of the knees, ankles, and toes, as well as inversion or eversion of the foot, are possible at this stage as well. Abnormal movements of the neck and shoulders and hip rocking and twisting are other components of a moderate form of Tardive Dyskinesia.

Severe Signs
In severe cases, facial features can become permanently disfigured, as well as limbs and trunks. The respiration muscles may also be affected, resulting in grunts, breathing difficulties, incapability of swallowing and speaking. Sometimes, the legs can be so severely affected that walking becomes difficult in this stage.

Paying attention to your body and its functions is imperative when taking any medication. Whether prescribed or over-the-counter, it’s important to research all ingredients and side effects, then compare which is the right choice for you.
