Tics and convulsion differ in etiology, but can be confused sometimes. Tics are one of extrapyramidal symptoms, characterized by sudden, intermittent, repetitive, involuntary or semivoluntary movements. Convulsion is abnormal involuntary contraction of the muscles. Sometimes convulsion is epileptic in nature, but not all epilepsy presents with convulsion.
