Epilepsy/Seizures: Seizures, also known as fits or convulsions, is a single occurrence of abnormal electrical activity in the brain, whereas epilepsy is a chronic neurological disorder characterized by recurrent seizures. The possible causes of epilepsy include traumatic brain injury, scarring on the brain after a brain injury, high fever, stroke, vascular diseases, lack of oxygen to the brain, brain tumours, and genetic disorders. Symptoms include mood changes, anxiousness, nausea, dizziness, weakness, headache, muscle jerking, spasms, loss of balance, teeth clenching, rapid blinking or eye movements, biting the tongue, confusion, and loss of consciousness.

Mood disorder: It is a mental health disorder which mainly affects a person's emotional state. A mood disorder is associated with episodes of mood swings ranging from manic highs to depressive lows. 

Migraine: Migraine is a neurological condition which is characterised by an intense, debilitating headache. Hormonal changes, stress, lack or excess of sleep, bright lights, loud sounds, and certain foods and drinks can trigger migraine headaches. Symptoms of migraine include throbbing pain in one particular area with varying intensity, nausea, vomiting, numbness or tingling sensation, difficulty speaking, and sensitivity to sound and light.
