The signs and symptoms of hydrocephalus can vary depending on severity and age of onset, however irritability (due to pain) and vomiting are common amongst infants with the condition. [19] Without treatment, congenital hydrocephalus can be fatal in infancy. [20]
Hydrocephalus can be classified via mechanism into communicating, noncommunicating, ex vacuo, and normal pressure hydrocephalus. Diagnosis is made by physical examination and medical imaging, such as a CT scan. [1] Hydrocephalus is typically treated through surgery. One option is the placement of a shunt system. [1]
Very high intracranial pressures are usually fatal if prolonged, but children can tolerate higher pressures for longer periods. [12] An increase in pressure, most commonly due to head injury leading to intracranial hematoma or cerebral edema , can crush brain tissue, shift brain structures, contribute to hydrocephalus , cause brain herniation ...
Normal pressure hydrocephalus (NPH), also called malresorptive hydrocephalus, is a form of communicating hydrocephalus in which excess cerebrospinal fluid (CSF) builds up in the ventricles, leading to normal or slightly elevated cerebrospinal fluid pressure.
High-altitude cerebral edema is a severe and sometimes fatal form of altitude sickness that results from capillary fluid leakage due to the effects of hypoxia on the mitochondria-rich endothelial cells of the blood–brain barrier. [25] The edema can be characterized by vasogenic cerebral edema with symptoms of impaired consciousness and ...
Microplastics are fragments that can range from less than 0.2 inch (5 millimeters) or about the size of a pencil eraser, to 1 nanometer. A strand of human hair is about 80,000 nanometers wide ...
Lumbar puncture can also be performed to measure the intracranial pressure, which might be increased in certain types of hydrocephalus. However, a lumbar puncture should never be performed if increased intracranial pressure is suspected due to certain situations such as a tumour, because it can lead to fatal brain herniation. [34]
Botulism can cause double or blurred vision, slurred speech, drooping eyelids and difficulty swallowing or breathing. As symptoms progress, the muscles become progressively weakened.
