What is a subarachnoid hemorrhage?
term for decline in intellectual functioning severe enough to interfere with a person’s relationships & ADLs
What is dementia?
Acute inflammatory disease of parenchyma (brain tissue); gray matter
What is encephalitis?
This brain structure likes stability
What is the hypothalamus?
Arachnoid mater and pia mater barrier to them ever dating because the river is too deep in this place
What is the subarachnoid space?
a tearing of veins between the brain surface and dural sinus
Accumulation of blood in dural space = space-occupying lesion
Chronic: 80% in elderly men, usually from falls; anticoagulation tx.
What is a Subdural Hemorrhage?

Without me all the brain information would not be shared
What is the thalamus?
Flows within the 4 ventricles providing shock absorption
What is the Cerebral Spinal Fluid, CSF?
Contralateral hemiplegia & hemiparesis
Global aphasia, sensory & motor loss
What occurs with a Middle Cerebral Artery (MCA) Lesion?
The neurofibrillary tangles are the accumulations of tau proteins that detach from the microtubules
What causes the decline of cognition in AD? the neurofibrillary tangles are the accumulations of tau proteins
Positive Brudzinski’s Sign
What is cervical flexion causes flexion of hips/knees?
If you haven't maintained the information for recall during a test you could blame it on this structure not doing it's job
What is the hippocampus?
This enters the base of the brain through the foramen magnum to bring O2 to the posterior aspect of the brain
What is the vertebral artery?
Wallenberg Syndrome (vertigo, nausea, dysphagia, ipsilateral ataxia, ptosis)

Inflammation of the meninges of brain & spinal cord
Viral most common; bacterial most severe
Inflammation & congestion can produce thrombosis and scarring
What is Meningitis?
This contains the Cranial & Spinal nerves with a Somatic and an Autonomic division
What is the Peripheral Nervous system?
Not to be out done by the vertebral artery, these supply O2 to the lateral and anterior part of the brain
What are the R & L Internal Carotid Arteries?
Language expression is lost; located in post. aspect of left frontal lobe
What is Broca's Aphasia?
A progressive disease with scarring (sclerosis) & degeneration of motor neurons in lateral spinal cord, brainstem, & cerebral cortex
What is ALS?
Types of meningitis and which is most severe?
