Shaking
Another possible symptom of a grand mal seizure is the shaking or jerking movements of the limbs, including legs and arms. These signs suggest the presence of convulsion caused by a disruption in your brain activities. The level of intensity would range from hardly perceptible and very mind to relatively intense and serious. In most cases, it can be noticed easily by someone else. Keep in mind to seek immediate medical attention to prevent more severe complications in the long run. [4]
