Other less common causes of death include pulmonary embolism due to an obstructed artery in the lungs , heart arrhythmia the heart beats too fast, too slow, or irregularly , or pneumonia due to breathing food or water. The cause of ALS is unknown, and there is no single test for the condition. Diagnosis of ALS is usually based on the confluence and progression of symptoms and through the ruling out of other diseases that can cause similar symptoms. This includes human immunodeficiency virus HIV , Lyme disease, and syphilis, as well as neurological disorders such as multiple sclerosis, post-polio syndrome and multifocal motor neuropathy.
There is no cure for ALS, but there are treatments available. Managing ALS usually involves treating the symptoms and providing supportive care to improve quality of life and prolong survival.
This may include things such as a feeding tube for nutritional purposes and breathing support with a ventilator. While there are some medications to treat the progression of ALS symptoms, their effectiveness, and mechanism of action are poorly understood. Medications in the context of ALS treatment are usually drugs designed to alleviate symptoms like fatigue, muscle cramps, and spasticity.

While leptin is historically known for its role in regulating hunger, energy expenditure, and overall energy balance, it also works as a cytokine, promoting the production of pro-inflammatory molecules, such as tumor necrosis factor TNF -alpha.
No cytokines were found to be significantly increased in ALS patients relative to healthy individuals. The researchers then assessed cytokine differences between patients with and without fast-progressing disease. The groups did not differ in any of the evaluated demographic and clinical features, except for rate of disease progression.
Further analysis revealed that the combination of all three markers allowed the correct identification of Additional studies in this model also revealed that this leptin drop was linked to a significant increase in the activation of AMPK, a known regulator of leptin production, in adipocytes of male and female mice and across different disease stages.
This link was also confirmed in human adipocytes grown in the lab, which showed a significant increase in activated AMPK levels and a significant reduction in leptin when exposed to blood from people with fast-progressing, sporadic ALS. In the early stages of ALS progression, patients tend to have weak muscles. They might be weak and soft, or they could also be stiff, tight, and spastic. Loss of muscle bulk is also common. These symptoms may occur in only a single region of the body, or mild symptoms could affect more than one part of the body.
The person might be fatigued, have poor balance, slur their words, have a weak grip, or trip when walking. This stage often occurs before a diagnosis is made. In the middle stages of ALS, the symptoms in the muscles become more widespread. Some muscles might become paralysed, while others are unaffected or simply weakened. Unused muscles can result in contractures, where the joints become painful, rigid, and even deformed.
If a person falls, they may not be able to get back up on their own. They are no longer able to drive, and will experience weakness in swallowing, as well as increased difficulty in managing saliva and eating. Weakness in the breathing muscles can result in respiratory insufficiency, especially in lying down. Some people experience uncontrollable and random crying or laughing bouts. By the final stages of ALS, most voluntary muscles have been paralysed.
Mobility, by this point, is severely limited. For example, symptoms may appear gradually over time, or they may occur rapidly and then plateau. The stages and strategies outlined below offer a general idea of the physical progression of ALS, the types of assistance needed as symptoms worsen, and the role caregivers can play.

Muscle cramping and twitching fasciculations occur, as does loss of muscle bulk atrophy. Symptoms may be limited to a single body region or mild symptoms may affect more than one region.
The person may experience fatigue, poor balance, slurred words, a weak grip, tripping when walking, or other minor symptoms.
Sometimes this stage occurs before a diagnosis is made. Assistance needed The person may need help with some physical tasks, and might benefit from the use of a cane, leg brace, or other simple device. Caregivers should: Provide assistance when asked. Review and update legal, financial, medical, and other affairs, and investigate government and insurance benefits. Begin to share the news of the ALS diagnosis with children, relatives, and friends.
Middle stages Physical effects Symptoms become more widespread. Some muscles are paralyzed while others are weakened or unaffected.
