Q

Lifespan considerations for older adults related to CNS age related changes

Brain vol
Mylin sheath
Thought process
Bal
Sensation
A

•Brain ⬇️ in volume: ⬇️ in neurons

•Myelinated axon length shortens
- slow delayed response to stimuli

• cognitive changes
-Slower thought process

•Mobility issues
-Poor bal

  • **Decreased sensation
    - Risk for injury

What are signs and symptoms of brain herniation
1. Ipsilateral pupil dilation: pupil sluggishly reactive indicates worsening neurological status  2. Irregular slow breathing
63
 after doing an MRI preforming angiography requiring lumbar puncture How long was the patient’s stay bedrest What happens if the patient still has a headache What does a persistent headache mean
After lumbar puncture patient must be bed rest 6 to 8 hours If patient displays headache bedrest required for 24 hours plus fluids If persistent headache it indicates a CSF leak
64
After a lumbar puncture That results in CSF leak what is done to clot and seal the preparation
After lumbar puncture with known CSF leak do blood patch Blood patch: is personal blood introduced to the epidural space that will clot and seal the perforation
