Amyotrophic Lateral Sclerosis (ALS) Early Symptoms, Causes, and Prognosis Amyotrophic lateral sclerosis (ALS) is a rare group of neurological diseases that mainly involve the nerve cells (neurons) responsible for controlling voluntary muscle movement. Voluntary muscles produce movements like chewing, walking, breathing and talking. The disease is progressive, meaning the symptoms get worse over time.

ATROPHY Atrophy is a form of cell adaptation in response to decreased trophic influences, decreased functional demands or decreased nutrition. Cellular Atrophy is a decrease in cell size caused by loss of subcellular organelles and substances.

Cerebral atrophy Cerebral atrophy is a common feature of many of the diseases that affect the brain.Atrophy of any tissue means a decrement in the size of the cell, which can be due to progressive loss of cytoplasmic proteins. In brain tissue, atrophy describes a loss of neurons and the connections between them.erebral atrophy is a common feature of many of the diseases that affect the brain.

atrophy Atrophy. the decrease in the size of an organ or tissue of the living organism of animals and man, accompanied by a disorder or cessation of functions. Atrophy is the result of a predominance of dissimilation over the processes of assimilation. Atrophy can be physiological and pathological, systemic and local.

Amyotrophic Lateral Sclerosis: Lou Gehrig's Disease Amyotrophic lateral sclerosis (ALS), commonly called Lou Gehrig's disease, is a progressive neuromuscular condition characterized by weakness, muscle wasting, fasciculations and increased reflexes.Approximately 30,000 Americans currently have the disease. The annual incidence rate is one to two cases per 100,000.myotrophic lateral sclerosis (ALS), commonly called Lou Gehrig's disease, is a progressive neuromuscular condition characterized by weakness, muscle wasting, fasciculations and increased reflexes.

Vaginal Atrophy (Atrophic Vaginitis) Vaginal atrophy is a change of the vagina that develops when there is a significant decrease in levels of the female hormone estrogen. The condition also is called atrophic vaginitis. Estrogen, which is produced by the ovaries, plays a vital role in keeping vaginal tissues lubricated and healthy.

Muscle Atrophy: Causes, Symptoms & Treatments Muscle atrophy is the loss or wasting of muscle tissue throughout the body. There are two basic ways in which this disease can form. The most severe form of this disease is neurogenic atrophy, a disease caused when an injury or disease harms the nerve which attaches to the muscle. This damage can occur quite suddenly.

- Muscle atrophy is when muscles waste away. The main reason for muscle wasting is a lack of physical activity. This can happen when a disease or injury makes it difficult or impossible for you to move an arm or leg.

What is ALS? ALS, or amyotrophic laterals sclerosis, is a progressive neurodegenerative disease that affects nerve cells in the brain and the spinal cord. A-myo-trophic comes from the Greek language. A means no. Myo refers to muscle, and Trophic means nourishment – No muscle nourishment. When a muscle has no nourishment, it atrophies or wastes away.

What Are the Causes of Brain Atrophy? Brain atrophy is shrinking of the brain caused by the loss of its cells, called neurons. Two types of brain atrophy can occur; generalized and focal. Generalized atrophy refers to neuron loss throughout the entire brain, and focal atrophy refers to neuron loss in a specific brain region.

Clinical Applications For Exam 3 Atrophy Muscular atrophy refers to a decrease in size of muscles. Individual muscle fibers decrease in size, and there is a progressive loss of myofibrils. Disuse atrophy is a muscular atrophy that results from lack of muscle use.

Muscle Atrophy Muscle atrophy takes place when a muscle partially or completely wastes away and its mass decreases. Most cases of muscle atrophy are usually results of other pre-existing medical conditions that include the loss of muscle mass as a side effect. Loss of muscle mass can be characterized by fatigue, extreme muscle weakness, or the actual shrinking of the physical body of the affected individual.

- 2. Epidemiology. Spinal muscular atrophy (SMA) is an autosomal recessive neuromuscular disorder characterized by the loss of motor neurons from the anterior horn of the spinal cord which leads to muscle weakness, hypotonia and ultimately muscle atrophy [ 1 ].

Muscle atrophy Muscle atrophy is defined as a decrease in the mass of the muscle; it can be a partial or complete wasting away of muscle, and is most commonly experienced when persons suffer temporary disabling circumstances such as being restricted in movement and/or confined to bed as when hospitalized.

Spinal muscular atrophy Spinal muscular atrophy is a group of disorders of the motor neurons (motor cells). These disorders are passed down through families (inherited) and can appear at any stage of life. The disorder leads to muscle weakness and atrophy.

- Cerebral atrophy refers to the progressive loss of brain cells over time. Atrophy refers to a decreased size or wasting away of any part of the body. Cerebral atrophy can happen in either the entire brain or in just one part of the brain and can lead to decreased brain mass and loss of neurological function. The symptoms of cerebral atrophy depend on the cause and location of cell death.

Spinal Muscular Atrophy Spinal muscular atrophy is a group of inherited diseases that affect the muscles responsible for voluntary movement in the body. This disease occurs when there is damage to the motor neurons, specialized nerve cells that facilitate communication with the muscles.

Muscle atrophy Muscle atrophy is defined as a decrease in the mass of the muscle; it can be a partial or complete wasting away of muscle, and is most commonly experienced when persons suffer temporary disabling circumstances such as being restricted in movement and/or confined to bed as when hospitalized.uscle mass is reduced as muscles atrophy with disuse. Muscle atrophy occurs by a change in the normal balance between protein synthesis and protein degradation. During atrophy, there is a down-regulation of protein synthesis pathways, and an activation protein degradation.

A to Z List of Neurological Disorders Spinal muscular atrophy (SMA) is a hereditary disease affecting the lower motor neurons. It is an autosomal recessive disorder caused by defects in the gene SMN1, which makes a protein that is important for the survival of motor neurons (SMN protein).pper motor neurons direct the lower motor neurons to produce movements such as walking or chewing. Lower motor neurons control movement in the arms, legs, chest, face, throat, and tongue. Spinal motor neurons are also called anterior horn cells. Upper motor neurons are also called corticospinal neurons.
