What type of disorder, Paralysis is
-
Nervous disorder
-
Functional Disorder
-
Vascular Disorder
-
Psychological Disorder
Correct Answer
A. Vascular DisorderExplanation
Paralysis is a condition characterized by the loss of muscle function in part of the body. Vascular disorder refers to any condition that affects the blood vessels, including blockages or damage that can lead to reduced blood flow. In the case of paralysis, it can be caused by a disruption in blood supply to the affected area, such as a stroke or blood clot. Therefore, paralysis is classified as a vascular disorder.Rate this question:

Which of the following causes unprovoked seizures in the patient?
-
Epilepsy
-
Paralysis
-
Stroke
-
Nervous Disorder
Correct Answer
A. EpilepsyExplanation
Epilepsy is the correct answer because it is a neurological disorder characterized by recurrent, unprovoked seizures. These seizures are caused by abnormal electrical activity in the brain, which can result in various symptoms such as convulsions, loss of consciousness, and sensory disturbances. Unlike paralysis, stroke, and nervous disorder, epilepsy specifically refers to a condition that causes unprovoked seizures in patients.Rate this question:

Abnormal and excessive discharge of nerve impulses in the brain is called
-
Paralysis
-
Epilepsy
-
Stroke
-
Nervous disorder
Correct Answer
A. EpilepsyExplanation
Epilepsy is the correct answer because it is a neurological disorder characterized by abnormal and excessive discharge of nerve impulses in the brain. This leads to recurring seizures, which can vary in severity and frequency. Paralysis, stroke, and nervous disorder are not accurate descriptions of this specific condition.Rate this question:

Which of the following would be active when the person is sleeping?
-
Sympathetic nervous system
-
Parasympathetic nervous system
-
Central nervous system
-
Somatic System
Correct Answer
A. Somatic SystemExplanation
The somatic system would be active when a person is sleeping. The somatic system controls voluntary movements and actions, such as turning over in bed or adjusting the pillow. During sleep, the body may still make these voluntary movements, even though the person is not consciously aware of them. The sympathetic and parasympathetic nervous systems, on the other hand, control involuntary functions and are generally less active during sleep. The central nervous system includes the brain and spinal cord, which are involved in both voluntary and involuntary processes.Rate this question:

The most common cause of dementia in the general population
-
Epilepsy
-
Vascular disease
-
Alzheimer's Disease
-
Head trauma
Correct Answer
A. Alzheimer's DiseaseExplanation
Alzheimer's Disease is the most common cause of dementia in the general population. It is a progressive neurodegenerative disorder that affects memory, thinking, and behavior. The disease is characterized by the accumulation of abnormal proteins in the brain, leading to the death of brain cells and the deterioration of cognitive function. While other conditions like epilepsy, vascular disease, and head trauma can also cause dementia, Alzheimer's Disease is the most prevalent and well-known cause.Rate this question:

Parasympathetic system is also called:
-
Fight-or-flight system.
-
Eat-drink-and-rest system
-
Autonomic nervous system
-
Somatic nervous system
Correct Answer
A. Eat-drink-and-rest systemExplanation
The parasympathetic system is responsible for promoting rest, relaxation, and digestion in the body. It works in opposition to the sympathetic system, which is responsible for the fight-or-flight response. Therefore, the term "eat-drink-and-rest system" accurately describes the functions of the parasympathetic system. The other options, such as "fight-or-flight system" (which is associated with the sympathetic system) and "autonomic nervous system" (which encompasses both the sympathetic and parasympathetic systems), are incorrect. The somatic nervous system, on the other hand, controls voluntary movements and is not related to the parasympathetic system.Rate this question:

Which of the following is a genetic disease that causes neurons in the brain to waste away and die?
-
Huntington's disease
-
Multiple sclerosis
-
Nervous breakdown
-
Epilepsy
Correct Answer
A. Huntington's diseaseExplanation
Huntington's disease is a genetic disorder that leads to the degeneration and death of neurons in the brain. It is caused by a mutation in the huntingtin gene, which produces an abnormal form of the huntingtin protein. This protein builds up in the brain, causing damage to the cells and leading to the characteristic symptoms of the disease, including involuntary movements, cognitive decline, and psychiatric symptoms. Huntington's disease is inherited in an autosomal dominant manner, meaning that a person with the mutated gene has a 50% chance of passing it on to their children.Rate this question:

Cerebral palsy affects neurons in which part of the body?
-
Eye
-
Brain
-
Muscles
-
Spinal cord
Correct Answer
A. BrainExplanation
Cerebral palsy affects neurons in the brain. This condition is caused by damage to the developing brain, typically before or during birth, which affects muscle control and coordination. The damage to the brain disrupts the normal communication between the brain and the muscles, leading to difficulties with movement, posture, and balance.Rate this question:

Dopamine is an important neurotransmitter. Which disease or disorder results when the neurons in the brain that produce dopamine die?
-
Parkinson'disease
-
Epilepsy
-
Stroke
-
Haemorrhage
Correct Answer
A. Parkinson'diseaseExplanation
Parkinson's disease is caused by the death of neurons in the brain that produce dopamine. Dopamine is a neurotransmitter that plays a crucial role in coordinating movement and regulating mood. When these dopamine-producing neurons die, it leads to a decrease in dopamine levels, resulting in the characteristic symptoms of Parkinson's disease, such as tremors, stiffness, and difficulty with coordination and balance.Rate this question:

Grand mal Seizures
-
Relaince on soporific drugs
-
Inability to regulate sleep wake cycles
Correct Answer
A. Inability to regulate sleep wake cyclesExplanation
Narcolepsy is a disorder characterized by the inability to regulate sleep-wake cycles. This means that individuals with narcolepsy have difficulty controlling when they fall asleep and wake up. They may experience excessive daytime sleepiness and sudden, uncontrollable episodes of falling asleep during the day. This can greatly disrupt their daily activities and overall quality of life. It is important for individuals with narcolepsy to seek medical treatment and adopt lifestyle changes to manage their symptoms effectively.Rate this question:

Treatment for epilepsy to eliminate or sharply reduce the frequency of seizures may involve all of the following except:
-
Cognitive-behavioral therapy
-
Narrow-spectrum and broad-spectrum antiepileptic drugs
-
Vagus-nerve stimulation
-
Surgery
Correct Answer
A. Cognitive-behavioral therapyExplanation
Cognitive-behavioral therapy is not typically used as a treatment for epilepsy. It is a form of psychotherapy that focuses on changing negative thoughts and behaviors, and it may be helpful for managing anxiety or depression that can be associated with epilepsy, but it is not a primary treatment for reducing seizures. The other options listed (antiepileptic drugs, vagus-nerve stimulation, and surgery) are commonly used treatments for epilepsy.Rate this question:

Diagnostic tests for epilepsy include all of the following except:
-
Simple blood test
-
EEG
-
Brain Scan
-
Wada test
Correct Answer
A. Simple blood testExplanation
Diagnostic tests for epilepsy typically include an EEG (electroencephalogram) to measure the electrical activity in the brain, a brain scan (such as an MRI or CT scan) to detect any abnormalities in the brain structure, and a Wada test to determine language and memory functions in the brain. A simple blood test is not typically used as a diagnostic tool for epilepsy, as it does not directly measure brain activity or detect any specific markers for the condition.Rate this question:

Gradually increasing pain and weakness and numbness in the hand or wrist that radiates up the arm suggest:
-
Amyotrophic lateral sclerosis
-
Carpal tunnel syndrome
-
Bloch-Sulzberger Syndrome
-
Dystonia
Correct Answer
A. Carpal tunnel syndromeExplanation
Gradually increasing pain and weakness, along with numbness in the hand or wrist that radiates up the arm, is a common symptom of carpal tunnel syndrome. This condition occurs when the median nerve, which runs through the carpal tunnel in the wrist, becomes compressed. The compression can lead to symptoms such as tingling, numbness, and weakness in the hand and arm. Other conditions listed, such as amyotrophic lateral sclerosis, Bloch-Sulzberger Syndrome, and dystonia, do not typically present with these specific symptoms.Rate this question:
