There are several millions of nerve cells in our brain that are responsible for passing electrical signals between each other and that all together contribute for the correct functioning of the brain. The interruption or overload of these signals can lead to seizures, and these have a consequent impact on the brain functions, like mood, memory, movement, among others.
There are many different types of seizures. What happens to you during a seizure depends on what part of your brain is affected. With some types of seizures you remain alert and aware of what’s going on around you, and with other types you lose awareness. You may have unusual sensations, feelings or movements. Or you may go stiff, fall to the floor and jerk.
