POLIOMYELITIS<br />Also called infantile paralysis<br />A disease that destroys the motor neurons and causes paralysis.<br />
Cause:<br />Poliomyelitis is caused by infection with a virus known as poliovirus (PV).<br />
Symptoms:<br /> 90% of polio infections have no symptoms at all.<br />
RABIES<br />Rabies is an infection caused by the rabies virus. This virus attacks the brain, causing severe inflammation (encephalitis) and death.<br /> <br />A person or animal can become infected with the rabies virus in one of a few ways, including:<br /> <br /><ul><li>Bites
Rabies victim<br />Symptoms may be headache, fatigue, fever and pain at the site of the bite can be present. Behavioral changes like apprehension, anxiety, agitation, irritability, insomnia and depression may also appear.<br />
MENINGITIS<br /> Meningitis is an inflammation of the meninges, the membranes that cover the brain and spinal cord. It is usually caused by bacteria or viruses, but it can also be caused by certain medications or illnesses.<br />
Causes:<br /> Many of the bacteria and viruses that cause meningitis are fairly common and are typically associated with other routine illnesses. Bacteria and viruses that infect the skin, urinary system, gastrointestinal or respiratory tract can spread by the bloodstream to the meninges through cerebrospinal fluid, the fluid that circulates in and around the spinal cord.<br />
Symptoms:<br />The first symptoms of bacterial or viral meningitis can come on quickly or surface several days after a child has had a cold and runny nose, diarrhea and vomiting, or other signs of an infection. Common symptoms include:<br />fever<br />lethargy (decreased consciousness)<br />irritability<br />headache<br />photophobia (eye sensitivity to light)<br />stiff neck<br />skin rashes<br />seizures<br />
Cerebral Palsy<br />is an umbrella term encompassing a group of non-progressive, non-contagious conditions that cause physical disability in human development.<br />
Causes:<br />• Infection During Pregnancy – rubella, cytomegalovirus, and toxoplasmosis can cause severe damage to the nervous system of the fetus and result in cerebral palsy.<br />• Jaundice – severe jaundice can result in brain damage<br />• Rh Incompatibility – can cause jaundice This is a condition where the mother's immune system attacks the fetus<br />• Oxygen Shortage – a shortage of oxygen during birth can cause brain damage to the child.<br />• Stroke – a stroke in the fetus can occur if the mother suffers from coagulation disorders<br />• Toxicity – drug or alcohol use can result in brain damage<br />• Bleeding – bleeding in the brain of the infant after birth can cause brain damage<br />• Kidney/Urinary Tract Infections – can also lead to brain damage<br />
Symptoms:<br /> CHARACTERISED BY THE FOLLOWING:<br /><ul><li>abnormal muscle tone, posture (i.e. slouching over while sitting), reflexes, or motor development and coordination.
There can be joint and bone deformities and contractures (permanently fixed, tight muscles and joints).
The classical symptoms are spasticity, spasms, other involuntary movements (e.g. facial gestures), unsteady gait, problems with balance, and/or soft tissue findings consisting largely of decreased muscle mass.
Scissor walking (where the knees come in and cross) and toe walking are common among people with CP who are able to walk, but taken on the whole, CP symptomatology is very diverse. </li></li></ul><li>

In Infants and Children<br />Fever (febrile seizures)<br />Brain tumor (rarely)<br />Infections<br />
Children and Adults <br />Congenital conditions (Down’s syndrome; Angelman’s syndrome; tuberous sclerosis and neurofibromatosis)<br />Genetic factors<br />Progressive brain disease (rare)<br />Head trauma<br />
In Elderly<br />Stroke<br />Alzheimer’s disease<br />Trauma<br />
