![]() if the abnormal rapid firing of impulses is taking Signs and symptoms will vary depending on which part of theīrain is affected. Small part of the brain, most commonly in the temporal lobe, and lasts a few Seizure activity and fully aware of what is happening to him. § Focal Onset Aware: This was previously known as There is also a third type of focal/partial seizure known as Focal to a bilateral tonic-clonic seizure. ![]() The seizure activity, a focal seizure is divided into Focal Onset Aware and Focal He was doing before the seizure activity.ĭepending on whether awareness is preserved or not during Seconds and after the seizure activity is over, the person continues doing what For others, heĪppears to be just blankly staring and daydreaming. He gets disconnectedįrom all his surroundings and gives no response to others. Things which he was doing before the seizure activity. Smacking or eyelid fluttering may be seen. § Absence Seizure: It is called an Absence seizureīecause there are rarely any obvious signs of seizure-like muscle stiffening, Seizure is rare and it lasts for less than 1 minute. The person’s body or parts of the body violently jerk. § Clonic Seizure: In this type of seizure activity Unlike Tonic- Clonic seizure, only The tonic part happens in this type of seizure and there is no Clonic phase. A person may fallĭown if seizure activity occurred while standing. Muscle tone is greatly increased and the muscles get stiffen. § Tonic Seizure: In this type of seizure, the That in Myoclonic seizure, the jerky movements could be stronger. Jerky movement that wakes us up as we were just falling asleep. It feels somewhat like what we normally sometimes experience a sudden It lasts for just 1 or 2 seconds.ĭuring this type of seizure activity, there is a brief shock-like jerky movement of muscles. ‘clonus’ means rhythmical jerky movements. § Myoclonic Seizure: ‘Myo’ means muscles and They are in some potentially harmful environment. People with such type of seizure must use protective gear like helmets while The person usually gets injuries due to the fall. And so, this is also known as a “ drop attack”. As a result, the person falls down during In this type of seizure, the muscles all ofĪ sudden lose their tonicity and become floppy making the skeletal muscles § Atonic Seizure: It lasts less than 15 seconds. It may appear bloody if the tongue or inner cheek bite is And when the mouth opens, theįoamy saliva comes out. Mixed with saliva, bubbles form in the saliva. When air enters during breathing and gets Saliva: When the mouth is forced shut, the salivary glands produce more The muscles of the bladder or bowel cannot hold urine or stool. ![]() Or bladder: This happens because the muscles get relaxed and due to which Relaxation which result in violent jerky movements (convulsion).īite: It occurs because the mouth is forced shut and the tongue or the inner cheek comes inīetween the teeth and as the lower jaw violently jerks, the canine tooth And there is alternate muscle contraction and This causes the continuous excitation to get interrupted with a small duration of relaxation. Tries to control the excessive excitation by superimposing the Inhibitory Muscles due to too much excitatory firing of impulses in the Tonic phase, the brain This phase lasts for about one minute and is characterized by the violent jerky movement of muscles. The muscles get contracted and stiffen and air rushes out from the vocal cord.ĭue to stiffening of the respiratory muscles and the person skin and lips mayĬlonic phase. A loud cry can be heard for a few seconds as all of a sudden, all The person loses consciousness andįalls down. Highly contracted as there is too much increase in the muscle tone due toĮxcessive excitatory firing of impulses. GTCS: This phase lasts for 10-20 seconds. It is the most common type of generalized As the name says “Generalised Tonic-clonic seizure”, the seizureĪctivity occurs in two distinct phases- The first phase is called the Tonic phase and the second phase is called the Clonic phase. § Generalised Tonic-clonic seizure (GTCS) Temporal, parietal, frontal, or occipital lobe of the brain. Seizure, the rapid firing of impulses is localized to a particular part or lobe, or hemisphere in the brain. Neurons in some specific part of the brain rapidly fire the impulses. Whereas, in focal or partial seizures, only some group of the WHAT IS THE DIFFERENCE BETWEEN GENERALISED SEIZURE AND FOCAL SEIZUREĪ generalized seizure is the rapid firing of impulses that take place in the neurons all (previously known as a Secondarily generalized seizure)
