Pathology of Hydrocephalus

Hydrocephalus is usually due to blockage of cerebrospinal fluid (CSF) outflow in the ventricles or in the subarachnoid space over the brain. In a person without hydrocephalus, CSF continuously circulates through the brain, its ventricles and the spinal cord and is continuously drained away into the circulatory system. Alternatively, the condition may result from an overproduction of the CSF fluid, from a congenital malformation blocking normal drainage of the fluid, or from complications of head injuries or infections. Compression of the brain by the accumulating fluid eventually may cause convulsions and mental retardation. These signs occur sooner in adults, whose skulls no longer are able to expand to accommodate the increasing fluid volume within. Fetuses, infants, and young children with hydrocephalus typically have an abnormally large head, excluding the face, because the pressure of the fluid causes the individual skull bones — which have yet to fuse — to bulge outward at their juncture points. Another medical sign, in infants, is a characteristic fixed downward gaze with whites of the eyes showing above the iris, as though the infant were trying to examine its own lower eyelids.

Hydrocephalus

Hydrocephalus , also known as Water on the Brain, is a medical condition. People with hydrocephalus have an abnormal accumulation of cerebrospinal fluid (CSF) in the ventricles, or cavities, of the brain. This may cause increased intracranial pressure inside the skull and progressive enlargement of the head, convulsion, and mental disability. Pediatric hydrocephalus affects one in every 500 live births, making it one of the most common developmental disabilities, more common than Down syndrome or deafness. It is the leading cause of brain surgery for children. There are over 180 different causes of the condition, one of the most common acquired etiologies being brain hemorrhage associated with premature birth. Pediatric hydrocephalus may also be a heritable condition, and mainly affects males. Hydrocephalus may be detectable during prenatal ultrasound examinations.
