Neurological Diseases

• temporary episode duration less than 24 hours
• impaired neuro functioning
• inadequite flow to a portion brain

• blood b/t skull and dura matter
• dura matter-outermost layer of meingi

blood collection b/t dura and the arachnoid membrane the second meningeal membrane

a hole made in the skull to relieve pressure by draining accumulated blood

• -bruising of tissue from back and forthe movement of head insult
• -or impact blunt object
• disruption of normal electric activity but brain is not perm injured

• more serious than concusion
• bruising of tissue along or just underneath brain surface
• perm damage may result
• may be associated with skull fracture
• CT Dx

• break in cranium
• can cause quadriplegia hemi or para

• partial paralysis of half of body
• casue can be fracture causeing pressure on motor area of brain

• loss of nerve function below waist
• paralysis of lower trunk and legs

• C5 damage
• paralysis arms hands etc

• deterioration of intervertbral disk
• intractable pain may result in some loss of motor function
• misalignment of vertebrae cause spinal nerve root scarring
• may cause spinal stenosis

nerve roots become trapped in the foramen as they leave the spinal canal

• -ruptured slipped
• -result from accumulated trama

• gelatinous center inside of vertebral disks that is surrounded by a circular wall structure
• an annulus

rupture of nucleus pulposus in disks L4- S3

• narrowing of the spinal canal or nerve root foramen
• -siatica

• headache
• -physiological factors
• 1-strain on muscles of face neck scale - tension headache
• 2- edema within the bv of head which changed arterial size- vascualr headache

• periodic severe headaches
• nausea vomiting anorexia visual symp
• factors
• heredity
• changes in cerebral blood flow

chronic abnormal intense episodes of increased elecritcal activity in brain

prolonged contraction of resp system that causes loos of 02 on extremeties

• progressive
• deficiency of dopamine
• other factors- injestion poision, encephalitis, major tranquilizers, antihypertensive drugs

• hereditary degeneration of cerebral cortex and basal ganglia
• progressive atrophy
• chorea
• autosomal dominant trait -unsexl linked

ceaseless uncontrolled involuntary movements

• fasiculations and atrophy of forearms and hands
• speech etc affecte but mind not affected

• temporary memory loss
• 1-6 hours

• degeneration of peripheral nerves
• factors:
• alcholism
• infectious diseases
• metabolic or inflammatory disorders

• Pain of the area innervated 5th cranial nerve
• some connection to tumor or MS, shingles

• disorder facial nerve -7th cranial
• sudden onset weakness paralysis face

• inflammatin meningies
• baacterial or viral

• inflammation brain tissue
• inflammation leads to edema and cell lysis
• cause: herpes viruses or MMR
• mostly misquito related onset

• acute rapid preogression of spinal nerves
• numbness/ pain in hands feet
• demyelination occurs
• autoimmune basis
• factors: resp infection, gastroenterisits

Loss of myelin sheath of nerve

viral infectio of the anterior horn cells of hte gray matter of the spinal crod and causes selective destruction of motor neurons

nerve defect that results in loss of speech

double vision

involuntary contraction or twitching of muscles
