Here’s a glossary of terms related to Hydrocephalus:

1. Hydrocephalus: A condition characterized by an accumulation of cerebrospinal fluid (CSF) in the brain’s ventricles, leading to increased pressure and enlargement of the head.
2. Cerebrospinal fluid (CSF): A clear, colorless fluid that surrounds the brain and spinal cord, providing cushioning and nutrients.
3. Ventricles: Cavities within the brain that produce and contain cerebrospinal fluid.
4. Shunt: A surgical device used to drain excess cerebrospinal fluid from the brain to another part of the body, typically the abdomen.
5. Obstruction: Blockage or constriction that prevents the normal flow of cerebrospinal fluid.
6. Aqueduct of Sylvius: A narrow channel in the brain that connects the third and fourth ventricles, allowing for the flow of cerebrospinal fluid.
7. Congenital: Present at birth.
8. Acquired: Developed or occurring after birth.
9. Symptoms: Signs or indications of a disease or condition.
10. Enlarged head: Abnormal increase in the size of the head, often a symptom of hydrocephalus in infants.
11. Intracranial pressure: Pressure inside the skull.
12. Neurological deficits: Impairments in neurological function, such as weakness or loss of sensation.
13. Ventriculoperitoneal (VP) shunt: A type of shunt that drains cerebrospinal fluid from the brain to the abdominal cavity.
14. Ventriculostomy: A surgical procedure in which a hole is made in a ventricle to allow for the drainage of cerebrospinal fluid.
15. Endoscopic third ventriculostomy (ETV): A minimally invasive surgical procedure to treat hydrocephalus by creating a new pathway for the flow of cerebrospinal fluid.
16. Chronic: Persisting over a long period of time.
17. Acute: Having a rapid onset and a short duration.
18. Meningitis: Inflammation of the meninges, the membranes that cover the brain and spinal cord.
19. Neurosurgeon: A surgeon who specializes in surgery of the nervous system, including the brain and spinal cord.
20. Cognitive impairment: Difficulty with mental processes such as thinking, learning, and remembering.
21. Gait disturbance: Abnormalities in walking or movement.
22. Developmental delays: Delays in reaching developmental milestones, such as sitting up, crawling, and walking.
23. Hydrocephalus ex-vacuo: A condition where there is an enlargement of the brain’s ventricles due to brain tissue loss.
24. Lumbar puncture: A procedure in which cerebrospinal fluid is collected from the lower back for diagnostic or therapeutic purposes.
25. Intracranial hemorrhage: Bleeding that occurs inside the skull, which can be a complication of hydrocephalus.
