Health and Neurological Disorders

Defects typically fall into three categories: WRONG (incorrect functionality), MISSING (absent functionality), and EXTRA (unintended features). Option D 'All the above' correctly includes all three categories. This classification helps in defect analysis and prevention.

Stuttering manifests as multiple fluency disruptions: sound repetitions ('l-l-l-look'), prolongations ('lllllook'), and pauses (filled 'um' or unfilled silences). All these are characteristic features, making 'All of the above' correct.

The cerebellum coordinates voluntary movement, balance, and posture. Damage causes ataxia - loss of muscle coordination, tremors, and balance problems. It doesn't control vital functions like heart rate (medulla) or hearing (temporal lobe), and isn't primarily involved in emotional response.

It is a case of loss of memory and capability of judgement as well as general physical impairment. It is caused by the augmentation of amyloid protein plaques in the brain resulting in the degeneration of neurons.

Insomnia is characterized by difficulty falling asleep or staying asleep, resulting in poor sleep quality. The question describes waking several times and trouble returning to sleep, which is maintenance insomnia. Narcolepsy involves sudden sleep attacks, sleep apnea involves breathing interruptions, and somnambulism is sleepwalking.

They have a much greater chance than average of having epilepsy, hypothyroidism, crossed eyes, cataracts, heart defects, hernias, a marked susceptibility to respiratory infections such as pneumonia, and childhood leukemia.

Newly born are hypotonic at birth and may have congenital anomalies, especially cardiac and gastrointestinal. Facial features include flat occiput, up-slanting palpebral fissures, furrowed tongue, short fingers and toes, and incurved fifth finger. 

Alzheimer disease is associated with memory loss and confusion, and may include language problems, poor judgment, agitation, and hallucinations. Brain atrophy is seen by MRI. There are no physical signs of the disease.

Amyotrophic lateral sclerosis (ALS), also known as Lou Gehrig's disease, is a progressive neurodegenerative disease that affects motor neurons in the brain and spinal cord. These neurons control voluntary muscle movement, making ALS a disorder of the nervous system. It does not primarily affect the cardiac, respiratory, or excretory systems.

Guillain-Barré Syndrome (GBS) is an autoimmune disorder where the immune system attacks the peripheral nervous system, specifically damaging the myelin sheath surrounding nerves. This causes muscle weakness, tingling sensations, and can progress to paralysis. It does not primarily affect the cardiac, excretory, or integumentary (misspelled as 'intugmentary') systems, though secondary complications may occur.

 Parkinson’s disease is caused by degeneration of brain neurons that are involved in movement control by making use of the neurotransmitter dopamine.

Multiple sclerosis (MS) is a chronic inflammatory demyelinating disease meaning that the myelin sheath of neurons is damaged. Symptoms of MS include visual and sensation problems, muscle weakness, and depression.

It is the inability to move a group of muscles in one side of the body. When hemiplegia is caused by a stroke, it often involves muscles in the face, arms, and legs. In elderly individuals, strokes are the most common cause of hemiplegia.

Parkinsonism is a neurological syndrome characterised by tremor, hypokinesia, rigidity, and postural instability. The underlying causes of parkinsonism are numerous and diagnosis can be complex. While the neurodegenerative condition, parkinson's disease is the most common cause of parkinsonism, a wide range of other etiologies may lead to a similar set of symptoms including some toxins, a few metabolic diseases.

It is a neurodegenerative genetic disorder that affects muscle coordination and leads to cognitive autism decline and psychiatric problems. It is a disorder passed down through families in which nerve cells in certain parts of the brain waste away or degenerate.
