Sudden, uncontrolled electrical disturbances in the brain lead to changed behaviour, body movements, and consciousness. This is known as a seizure. Most seizures last for 30 seconds to 2 minutes. However, if they last longer, that’s a medical emergency.
Patients with a history of head injury, meningitis, and previous seizures are at higher risk. There are two main types of seizures:
Focal seizures: It affects only one part of the brain. it can be accompanied by loss of consciousness sometimes.
Generalized seizures: These involve the whole brain.
If someone gets seizures frequently, it is termed epilepsy.
Nerve cells or neurons are responsible for the transfer of electrical impulses to and from the brain. all that we see, smell, hear and perceive are communicated through these nerve cells. We can take them as the electrical wiring of the house. When anything disrupts this flow of information, the brain begins to function differently giving rise to seizures.
A seizure happens in 3 phases:
Aura: It is a small partial seizure that alters the sense of smell, vision, perception, hearing and also emotions.
Ictus: It is the phase when the actual seizure happens.
Postictal phase: It is the post-seizure phase. The person feels disoriented and drowsiness.
You are prone to getting seizures if you have
The following are the symptoms of a seizure:
Doctors go for the neurological examination to assess the mental condition of the patient. They usually test for motor skills and mental functions. They may also suggest a blood test to confirm if the seizures are because of diseases like meningitis. If the doctor detects abnormal brain functions, they may suggest EEG, CT scan, fMRI, PET, SPECT, and various neuropsychological tests. Since seizures can start from any part of the brain, it becomes important to pinpoint the origin. For this, the doctors use analytical tools like SPM, curry analysis, and MEG.
Seizures can affect any age group. If left untreated, they can be life-threatening. Some of the complications related to it are:
Doctors avoid treating someone with just a single case of a seizure. In many cases, that is an isolated incident and never again happens in life. However, if you have a recurrent case of seizures, the doctor may opt for medicines or surgery. Seizures are a complex disease. It is hard to determine which part of the brain is involved. So, doctors go for the permutation and combination of the drugs to find the right one for you.
Basically, seizures are treated with

About 10 million people in India suffer from some kind of seizures.
Bone Cancer is one of the rarest cancers in the world and usually occurs in the large bones of arms and thighs.
Dialysis is a procedure in which the blood is filtered mechanically without the help of the kidneys. If the kidneys are not functioning properly then Dialysis will take over the function of the failed kidneys.
Bladder infection or cystitis is inflammation and disease within the urinary bladder. Bacteria are the most common causal organism for the bladder infection.
Fever with seizures can be due to brain fever
