Epilepsy is probably what you are referring to.
It can cause a seizure.

Neurons conduct electrical impulses in the brain. Neuroglia are cells that support the neurons. These cells undergo mitosis where neurons do not. Brain tumors are formed from neuroglia cells because they mitosis.
sensory neurons
Sensory neurons carry impulses from the sense organs to the brain and the spinal cord . Motor neurons carry impulses from the brain and spinal cord to muscles or glands.
Glial cells do not conduct electrical impulses (as opposed to neurons, which do). The glial cells surround neurons and etc

electrical impulses
Seizures involve abnormal electrical impulses of the brain. There are likely other conditions related to abnormal electrical impulses. For instance, people who get migraines often show abnormalities on EEG as well.
Contact between neurons, as you put it, is achieved through electrical impulses towards and from your brain.
Neurons conduct electrical impulses in the brain. Neuroglia are cells that support the neurons. These cells undergo mitosis where neurons do not. Brain tumors are formed from neuroglia cells because they mitosis.

Convulsions/seizures are caused by abnormal electrical activity in the brain. For a bit of background, the brain is part of the central nervous system, which controls and 'instructs' the body on what to do. The brain sends these instructions out using electrical impulses and signals. If the brain becomes confused, for whatever reason, the electrical impulses may begin to send abnormal impulses to the wrong places and via the incorrect neurons. This causes the body to get confused and results in abnormal twitching and convulsing. People with a medical condition called epilepsy have an abnormal brain electrical activity giving rise to epileptic seizures. Seizures/convulsions can also be caused by a brain tumour or another nervous system disorder. It is vital every seizure is reported to your medical practitioner. If the seizure last for longer than normal, or if it is your first seizure, seek urgent medical assistance or phone for an emergency ambulance.

Neurons and synapses relay information between the brain and eyes and ears. Neurons take in signals from your eyes and ears, and the electrical impulses are transferred to the brain to be processed into thought and sensation. The brain also sends impulses to the eyes and ears to make them function.
Neurons send electric impulses to your cells via the dendrites. The Axons carry the electrical impulses away from the cell. This process sends out signals to your brain for all of your body processes such as muscle movement.
