Antipsychotic drug side effects for persons with intellectual disability

Antipsychotic drugs are the most frequently prescribed of the psychotropic drugs among the intellectually disabled (ID) population. Given their widespread use, efforts to systematically assess and report side effects are warranted. Specific scaling methods such as the Matson Evaluation of Side Effects (MEDS), the Abnormal Inventory Movement Scale (AIMS), and Dyskinesia Identification System Condensed User Scale (DISCUS) are reviewed. Symptom patterns and a focus on additional research are discussed. While progress has been made, more and more systematic methods to research these problems are necessary.
