Chapter 11 Neural Function Flashcards
Meningitis is an inflammation of ?
Meninges covering the brain
Another name for a stroke is ?
Cerebrovascular accident
The greatest risk factor for hemorrhagic stroke
Hypertension
A brief interruption of brain function frequently caused by a fall or trauma to the head is called ?
Concussion
Which of the following is a chemical which crosses the gap between one neuron and the next neuron, or between the neuron and a muscle
Neurotransmitter
Is the correct term for the inability to speak
Aphasia
Is a syndrome of recurring episodes of excessive electrical activity of the brain commonly causing involuntary contraction of skeletal muscles
Seizure disorder
Pain, as described by the patient is ?
Subjective and individualized
Intracranial pressure is present when cerebrospinal fluid accumulates in the skull when the patient has this condition
Hydrocephalus
Treatment for hydrocephalus includes
Surgery to insert a shunt
Is a debilitating Nuero inflammatory disease that involves an abnormal immune mediated process directed against the CNS, causing progressive and irreversible demyelination of brain, spinal cord, and cranial nerve neurons
Multiple sclerosis
The inflammatory damage occurs in diffuse patches throughout the nervous system and slows or stops nerve impulses. As the disease progresses, the Brain cortex atrophies, and scar tissue plaque develops throughout the white matter
Multiple sclerosis
Are often called mini strokes because these neurologic deficits mimic a cerebrovascular accident or stroke except that the deficits resolve within 24 hours.
TIA
Is most often caused by viral infections associated with enterovirus, West Nile virus, influenza, HIv, and herpes
Meningitis
Also called Lou Gehrig’s disease, is a progressive disease that Involves damage to the upper motor neurons of the brain stem and spinal cord that control voluntary movement.
Amyotrophic Lateral sclerosis AlS
Is an infarction of the brain often called a brain attack
CVA
_________ Are the most common, ________ are the deadliest
Ischemic stroke
Hemorrhagic stroke
Optimally treatment should be delivered within 3 hours of symptom onset
CVA
Are treated with thrombolytic agents to dissolve any clots and aspirin to limit platelet activity
Treatment for ischemic stroke
Surgical repair for aneurysms or arteriovenus malformations and blood removal may be required in patients with
Hemorrhagic stroke
May also be administered with either type of CVA to reduce cerebral edema, antihypertensive agents may be used cautiously to reduce blood pressure slowly
Hypertonic solution
Develop between the dura and the arachnoid and are frequently caused by a small venous tear
Subdural hematoma
With _______, manifestations of neurological deficits present within 24 hours of an injury, progresses rapidly and has a high mortality rate
Acute subdural hematoma
With _____, ICP increases over a period of about a week after the injury
Sub-acute hematoma
With_______, manifestations develop several weeks after an injury because of a slow leak, more common in elderly adults because of brain atrophy
Chronic subdural hematoma
Result from bleeding between the dura and skull, usually caused by arterial tear
Epidural hematoma
Typical symptom pattern for _______, is a brief loss of consciousness, followed by a short period of alertness, then loss of consciousness
Epidural hematoma
Results from spontaneous firing of abnormal neurons and is characterized by at least 2 seizures that occur more than 24 hours apart for which there is no underlying or correctable cause.
Epilepsy
Seizures that last more than 5 minutes or subsequent seizures that occur before the individual has fully regained consciousness
Status epilepticus
Are called partial seizures and occur in one part of the brain
Focal seizures
Are a result of abnormal neuronal activity on both sides of the brain
Generalized seizure
The individual having a generalized seizure may be confused, be fatigued, have a headache, experience muscle soreness, and fall into a deep sleep in the period following the seizure referred to as
Postical period
Acetylcholine
Dopamine
Norepinephrine
Serotonin
Glutamate
GABA
Endogenous opioids
Neurotransmitters
Many of the genes associated with _____ are also identified in people with autoimmune diseases such as type 1 diabetes, RA , or systemic lupus erythematosus
MS
When approximately 80% of the dopamine producing cells are destroyed, movement issues develop which typically include tremors or the hands and feet
Parkinson’s disease
Levadopa
Dopamine agonists
Monoamine oxidase B inhibitors catechol O methyltransferase inhibitors
Anticholergenic agents
Increase dopamine levels
Deep brain stimulation with an implanted pacemaker device and lesional surgery
Treatments for Parkinson’s
People who have ______ typically have higher than normal levels of glutamate, chemical messenger in the brain, in their CSF.
ALS
