Cysts are small fluid filled sacs that can develop on organs inside the human body. Brain cysts are typically caused by developmental abnormalities or complications present at birth, causing them to be medically classified as primary brain cysts. Cysts that develop later in life due to injury or head trauma are known as secondary brain cysts. Depending on the size and location of the abnormality, brain cysts can cause a variety of symptoms.
Sensory Changes
People with brain cysts typically develop sensory changes such as double or blurred vision and hearing problems, according to the National Institute of Neurological Disorders and Stroke. Since the ear also controls balance, individuals with a brain cyst may also experience problems with dizziness, walking and balance as a result of the growth on varying areas of the brain.
Symptoms Due to Pressing on the Brain
The majority of symptoms caused brain cysts are caused by the growth pressing and applying pressure to the brain, resulting in a headache, notes the National Institute of Neurological Disorders and Stroke. Patients may also develop seizures of the growth interferes with electrical activities in the brain. Abnormal electrical activity within the brain usually results in chronic seizures or sudden muscle jerks.
Hydrocephalus
Some brain cysts can result in hydrocephalus, a medical condition in which liquid flowing out of the cranial cavity is impeded, which causes an increase in intracranial pressure, according to DrugInfonet.com. Symptoms of hydrocephalus include nausea, vomiting and weakness. Patients who develop hydrocephalus may also experience drowsiness, irritability, confusion or the loss of consciousness.
Musuclar Symptoms
Brain cysts may also cause muscular problems within the body if they are near the spinal cord or brain stem. Depending on the cyst location, the back, neck, arms or legs may be affected. In addition, the affected portion of the body may experience weakness, paralysis, tingling or numbness. Patients who experience these symptoms should contact a medical professional immediately.
