Hope for the life of sma patients ==================== sma disease is a progressive genetic disease that affects the nervous system and muscles, as soon as people find out that their child is suffering from sma disease, the first question that comes to their mind is whether this disease causes death, what is the life expectancy of sma patients, they think that their world is over and there is no other way.. you are worried about sma, read this article till the end.... although sma is considered a rare disease and The probability of getting it is low, but with the loss of certain nerve cells called lower motor neurons, it causes movement and nerve problems in the patient. In fact, muscle weakness and the death of muscle cells is a problem caused by sma disease, because the disease is progressing in a way, as the patient worsens, it connects more difficult conditions to the motor nerve cells. Cell control of muscle movement, movements such as swallowing, walking, breathing and crawling... \[toc\] types of sma disease and life expectancy of sma patients in each group sma disease has 5 different types (0, 1, 2, 3, 4), of course, some doctors do not consider type 0 of this disease as separate from the other categories, but it should be said that the life span of sma patients and also the limitation of movement in these patients will be different depending on the type of sma and the patient's age, which is a factor of the kind that we will talk about here... ### types of sma and life expectancy in these patients sma type zero: this type of sma patients has a lot in common with other types, type 0 sma disease is the most severe type of this disease, the unusual issue in this group is the age of onset of the disease that begins before the age of birth, babies are born with motor and muscle problems and are unable to acquire motor skills, they often survive until the age of six months with breathing problems.. Type zero patients, as said, the cause of the severity of the disease is estimated to be less than six months... #### sma type one: The most common type of sma type 1 is between 50 and 70% of patients in this group and is considered a very severe type. In general, the younger the age of onset of the disease, the more severe it is.. The life expectancy of these children and infants (life expectancy of sma type 1 patients) is about 8% low due to the severity of the disease and about 8% of them live before the age of two years.. Only before the age of 4 years, but with breathing and nutritional care, the life expectancy can be increased... in this group it increases.... This group shows the disease with evidence such as muscle weakness and muscle atrophy, as well as decreased motor power, these children cannot sit without support... #### sma type 2 disease The second type of SMA patients start their symptoms and disease between 7 and 18 months of age, these patients may be born with weak muscle tone at the beginning of life or face this weakness in muscle tone in the first months of their life... These babies and children may gain some muscle and movement abilities over time, such as sitting without help and independently, but few of them are able to shake and stand without problems... It may appear or spread... The situation in these patients is evaluated differently. may depending on the age of diagnosis in these patients, the lifespan of sma type 2 patients is different from other groups, many of these people grow up to the teenage years and even with proper treatment and care they can live well into adulthood... The curvature of the spine and the abnormality of the spine of these patients is due to the weakness of the three types of S## muscles... In the third type of these patients, symptoms usually start after 18 months or in some cases do not appear until the beginning of childhood... This group of children alone able to they are walking, but the tendency of this group to fall is high, in other words, this group may fall a lot, they face problems in climbing stairs and running, and in general, it can be said that this group of people in this age group have stronger arms.. Although they are independent, some of them can walk until adulthood, rehabilitation and support are considered to help these children.... Breathing and swallowing problems are less common in them, but In general, such conditions should be expected for patients.. #### type four sma Another type of sma patients is type 4, which we will talk about and the life expectancy of sma type 4 patients. We also try to talk about Spiranza and other SMA treatments to give parents a better perspective on these dear children. Neurology Clinic Dr. Majid Kihani Fard smanewstoday
