Which of the following disorders is an abnormal accumulation of fluid within the ventricles of the brain that results in an enlarged head?
Overview. Hydrocephalus is a condition characterized by an abnormal accumulation of cerebrospinal fluid (CSF) within the ventricles of the brain.
What happens when degeneration of nervous tissue occurs?
Breakdown of nerves can affect your senses. You might have reduced or lost reflexes or sensation. This leads to problems with movement and safety. Slowing of thought, memory, and thinking is a normal part of aging.
What is communicating hydrocephalus?
Communicating hydrocephalus occurs when the flow of cerebrospinal fluid (CSF) is blocked after it exits the ventricles. This type of hydrocephalus may result from a thickening of the arachnoid around the base of the brain, which blocks the flow of CSF from the spinal to the cortical subarachnoid spaces.
Why do schizophrenics have larger ventricles?
Conclusions: Thalamic shrinkage, especially of medial nuclei and the adjacent striatum and insular cortex, appear to be important contributors to ventricular enlargement in schizophrenia.
How long does it take for nerves to regenerate?
Regeneration time depends on how seriously your nerve was injured and the type of injury that you sustained. If your nerve is bruised or traumatized but is not cut, it should recover over 6-12 weeks. A nerve that is cut will grow at 1mm per day, after about a 4 week period of ‘rest’ following your injury.
Are dogs with hydrocephalus in pain?
Some dogs show no symptoms at all of hydrocephalus. Although, if it goes untreated and fluid continues to build in the skull, it’s likely that signs of pain and other symptoms will appear. Sometimes a puppy’s head will appear enlarged because the skull hasn’t fused yet.
Is communicating hydrocephalus serious?
Communicating hydrocephalus (non-obstructive hydrocephalus) is caused by inadequate reabsorption of CSF. The excessive accumulation of CSF results in an abnormal enlargement of the spaces in the brain called ventricles. This causes potentially harmful pressure on the tissues of the brain.
What are the symptoms of communicating hydrocephalus?
Physical signs and symptoms
- Nausea and vomiting.
- Sleepiness or sluggishness (lethargy)
- Irritability.
- Poor eating.
- Seizures.
- Eyes fixed downward (sunsetting of the eyes)
- Problems with muscle tone and strength.
