5.3 Nervous system diseases

What pathogens most commonly cause encephalitis according to the provided text?. It is primarily caused by viruses such as Herpes simplex and Epstein-Barr. It is primarily caused by fungi such as Candida albicans and Aspergillus. It is primarily caused by bacteria such as Streptococcus and Tuberculosis. It is primarily caused by parasites such as Plasmodium and Leishmania spp.

Which of the following describes the common signs and symptoms of encephalitis?. Fever, severe headache, drowsiness, mental confusion, and heavy hallucinations. Persistent coughing, chest pain, shortness of breath, and severe lung bleeding. Severe joint pain, intense muscle stiffness, bone fractures, and inflammation. Rapid weight loss, chronic diarrhea, severe stomach ulcers, and poor digestion.

What specific biological mechanism is primarily associated with Alzheimer's disease?. Deposits of beta-amyloid protein form plaques and tau protein causes tangles. Dopamine depletion in the brain stem causes severe continuous resting tremors. Excessive electrical discharges cause brief episodes of involuntary movements. Primary tumors known as astrocytomas develop rapidly in the cerebral cortex.

Which signs are characteristically observed in patients diagnosed with Alzheimer's disease?. Memory loss, impaired reasoning, spatial issues, and not recognizing known faces. Unilateral throbbing headache, severe photophobia, phonophobia, and visual auras. Sudden loss of consciousness, involuntary movements, and unusual sensory feelings. Severe resting tremors, intense muscle stiffness, and great postural instability.

How can individuals potentially reduce their risk of developing Alzheimer's disease?. By engaging in mental activities, regular exercising, and controlling blood pressure. By completely avoiding intense odors, skipping meals, and reducing estrogen intakes. By undergoing intense radiation therapy and scheduling regular brain biopsy testing. By ensuring they are frequently vaccinated against common strains of deadly viruses.

How does the provided text primarily define the neurological condition known as epilepsy?. A serious pathology consisting of frequent seizures due to excess electrical discharges. A cognitive disorder due to mutations altering the amyloid precursor molecule structures. An inflammation of the human brain triggered by viruses, bacteria, fungi, or protozoa. An idiopathic nervous condition causing motor problems like resting tremors and rigidity.

What is the correct first aid protocol if you observe someone having an epileptic seizure?. Put soft clothing under their head, lay them on their side, and ensure they are breathing. Place a hard object in their mouth, hold them very tightly, and prevent all their movement. Administer oral analgesics, offer them a glass of water, and forcefully ask them to stand. Immediately call an ambulance even if the severe seizure lasts less than two full minutes.

Which combination of factors is known to frequently trigger an intense migraine episode?. Skipping your meals, red wine, intense odors, lack of deep sleep, and stress conditions. Excessive sugar intake, high cholesterol levels, sedentary lifestyle, and heavy eating. Severe viral infections, aggressive autoimmune responses, and drinking contaminated water. Beta-amyloid plaques, tau protein tangles, early genetic mutations, and general brain aging.

What is an "aura" and what percentage of migraine patients typically experience it?. About 25% of patients experience visual auras, partial blindness, or strange light flashes. About 50% of patients experience severe auditory hallucinations and complete sudden deafness. About 75% of patients experience a complete physical paralysis of their lower extremities. About 90% of patients experience permanent language loss and severe memory daily disruptions.

What is the average age of onset and the primary known cause of Parkinson's disease?. Average age of 57; the exact cause is completely unknown but genetics might play a key role. Average age of 25; it is exclusively caused by severe head trauma occurring during childhood. Average age of 65; it is definitively caused by a complete lack of beta-amyloid in the brain. Average age of 15; the main known cause is a severe bacterial infection of the nervous system.

What are the characteristic physical motor symptoms associated with Parkinson's disease?. Noticeable tremors at rest, extreme stiffness, slow movements, and postural instability. Sudden absolute loss of consciousness, brief muscle spasms, and unusual physical sensations. Unilateral throbbing brain pain, extreme light sensitivity, nausea, and visual disruptions. Extremely high fever, deep daytime drowsiness, severe confusion, and uncontrollable vomiting.

Which specific types of primary brain tumors are explicitly mentioned in the text?. Dangerous astrocytomas, ependymomas, and medulloblastomas are common primary brain tumor types. Aggressive melanomas, carcinomas, and sarcomas are the most common primary brain tumor types. Malignant lymphomas, leukemias, and myelomas are primary tumors of the central nervous system. Harmless lipomas, fibromas, and osteomas are common benign primary tumors of the spinal cord.

What directly causes many of the severe symptoms associated with central nervous system tumors?. They are related to high intracranial pressure, causing headache, nausea, and sudden vomiting. They are related to sudden drops in blood pressure, causing fainting, fatigue, and weakness. They are related to severe essential nutrient deficiencies, causing massive bone loss fractures. They are related to the massive overproduction of dopamine, causing resting motor hand tremors.

Which specific tests and medical treatments are used to diagnose and treat severe encephalitis?. Tests include spinal taps and EEGs; treatments use antivirals and anticonvulsants. Tests include bone biopsies and ECGs; treatments use high dose radiation therapies. Tests include rapid eye movement checks; treatments use severe physical amputations. Tests include daily glucose measurements; treatments use heavy experimental sedatives.

According to the text, what are the primary ways individuals can help prevent encephalitis?. It can be prevented by getting vaccinated, eating a balanced diet, and washing hands. It can be prevented by strictly avoiding all sunlight exposure and wearing heavy hats. It can be prevented by drinking large amounts of coffee and avoiding cardiovasculars. It can be prevented by removing the appendix early and constantly resting in dark rooms.

What is the fundamental difference between focal and generalized types of epilepsy?. Focal seizures affect limited cells; generalized epilepsy involves the entire brain. Focal seizures affect the entire spine; generalized epilepsy involves just the legs. Focal seizures affect memory formation; generalized epilepsy involves only the eyes. Focal seizures affect internal organs; generalized epilepsy involves external tissues.

When applying first aid to a person having an epileptic seizure, when MUST you call 911?. If the person struggles to breathe, lips turn purple, or the seizure lasts >5 minutes. If the person instantly falls to the ground, blinks rapidly, or looks mildly confused. If the person takes a very deep breath, closes their eyes, or gently falls right asleep. If the person completely ignores your questions, yawns twice, or stretches their arms.

What specific factor can frequently trigger a severe migraine episode exclusively in women?. Fluctuations in estrogen concentrations like menstruation, pregnancy, and menopause. Fluctuations in dopamine concentrations like intense sadness, grief, and long crying. Fluctuations in serotonin concentrations like extreme happiness, joy, and loud laughs. Fluctuations in melatonin concentrations like sudden sleepiness, yawning, and resting.

What specific environmental and care measures are recommended for Alzheimer's patients?. Using bright rooms, visible clocks, monitoring systems, and daily caregiver assistance. Using dark quiet rooms, avoiding any external noises, and providing total isolations. Using heavy restraints, prescribing constant sleeping pills, and locking all the doors. Using loud alarms to keep them awake, forcing intense exercises, and limiting waters.
