###Human: My 2. 5 month old kid has tongue tremors. Is this due to SMA? ###Assistant: Hello,  Welcome to icliniq.com. History noted as above, your 2.5-month-old has developed tongue tremors. Please provide me more detailed history such as preterm or full term, birth weight, normal delivery or LSCS. How is her weight? Is she gaining weight and let me know more about family history or any other in the family suffering from SMA (spinal muscular atrophy). SMA is confirmed only by Genetic testing or by muscle study. There are many types of SMA some of them develop symptoms later in life and a few develop in early life. Keep a watch on her development like head holds muscle tone and power and let me know me know if tongue fasciculation increases and the child becomes more hypotonic.
