Neurological disorders & symptoms

Updated July 19, 2017

Every action or response the human body makes is controlled by the nervous system. Neurological disorders can appear suddenly and can be caused by things like infections and birth defects. Consult with a medical professional if you experience any of these signs and symptoms.


Meningitis is caused by bacterial and viral infections of the membranes surrounding the spinal cord and brain. Signs of meningitis can appear suddenly and include high fever, persistent headache, nausea and vomiting. Changes in normal behaviour like increased fatigue and confusion are also reported. Infants can also contract meningitis and display a fever, irritability, and fatigue. If you or anyone you know experiences any of these symptoms, seek medical attention.


ADHD stands for Attention Deficit-Hyperactivity Disorder and is a neurological behaviour disorder. ADHD affects between 3 and 5 per cent of children in the U.S. according to National Institute of Neurological Disorders. Sufferers have trouble staying focused on a task and exercising appropriate inhibition. Symptoms of ADHD include excessive talking, leaving projects and tasks unfinished, fidgeting and difficulty paying attention. These symptoms most often appear in childhood but can also be diagnosed in adults.

Bell's Palsy

Bell's Palsy is characterised by a temporary paralysis of the face which is typically caused by trauma or damage to the nerves of the face. Bell's palsy is the No. 1 cause of facial paralysis. In rare cases it can affect both sides of the face but it's most often one side caused by a single nerve. Symptoms of Bell's palsy appear suddenly and have usually peaked with 48 hours. These symptoms may include twitching, drooping in a corner of the mouth or an eyelid, and drooling.

Multiple Sclerosis

Multiple sclerosis is an unpredictable disease with complications and symptoms that can range from minimal to devastating. The exact cause of MS is unknown but its believed to be caused by the immune system attacking myelin, the body's nerve insulator. Initial symptoms of MS are double and blurred vision, muscle weakness, and poor coordination. In the worst cases, MS causes partial and complete paralysis.


Epilepsy is a disorder that occurs when the nerves of the brain begin firing abnormally. Epilepsy is caused by an disruption in normal neuron activity. Neural activity can be disrupted by numerous things including abnormal nerve pathways in the brain, tumours, meningitis, dementia, and an imbalance of neurotransmitters or chemicals that transport signals to the nerves. This can sometimes cause odd sensations, behaviour and emotions. Convulsions, loss of consciousness, and muscle spasms are also symptoms of epilepsy.
