Post concussion syndrome
is a set of symptoms that a person may experience for weeks, months, or occasionally up to a year or more after a concussion ( mild or severe).Symptoms may be headache; cognitive, such as difficulty concentrating; and emotional and behavioral, such as irritability. These symptoms are often vague and missed. But are consistent with the disease. A diagnosis of post concussion syndrome cannot be made without these symptoms or clinical signs of the same.
