Fragile X syndrome, also known as Martin-Bell syndrome, is a rare genetic disorder that is one of the leading causes of autism and similar developmental disabilities. Fragile X syndrome is caused by a genetic mutation in the FMR1, which is responsible for producing a protein that aids brain development. The genetic mutation damages the FMR1, which means that the essential protein it develops is never created, which reduces brain development.
Unfortunately, there is currently no exact cure for Fragile X syndrome (FXS), and children born with the disease will have it for their entire lives, putting them at high risk for developmental problems. However, FXS is not a life-threatening condition, and there are treatments that can help manage symptoms, giving your child a chance at a fairly normal life.
Because children with FXS will have developmental delays, they will also have physical ones. As such, everyone with FXS will need physical therapy and speech therapy to teach them essential things like walking, talking, and swallowing. Physical therapy can also help strengthen the arm, leg, and core muscles that your child needs to have a normal childhood.
In addition to speech and physical therapy, they may also need occupational therapy. Occupational therapy will teach your child practical, everyday things like how to interact with others and activities of daily living. While occupational, speech, and physical therapy all have similar developmental goals, they are administered by different professionals.
In addition to therapy, children with Fragile X syndrome will likely require mood stabilizers. You see, FXS affects the part of the brain that regulates mood, which means children with the condition may be erratic and unstable. Therefore, mood stabilizers, such as lithium carbonate or lamotrigine, may be necessary.
Along with an unstable mood, children with FXS will have a very hard time concentrating and focusing. Therefore, they may need ADHD medications, such as methylphenidate or amphetamines. If your child has Fragile X syndrome, they will already have a hard time learning new things, and ADHD can make it even more difficult.
Obsessive-compulsive disorder, OCD, is another common side effect of Fragile X syndrome. It is not entirely clear why FXS causes OCD, but it is a common side effect nonetheless, especially in females. Additionally, children with FXS will have a harder time regulating and overcoming OCD because the part of their brain that can control it may not be fully developed. Therefore, they may need OCD medications, such as clomipramine or fluoxetine.
Finally, there is a high likelihood that your child with FXS will also experience trouble sleeping due to their ADHD and inability to regulate their own mood. To combat this, you can try over-the-counter sleep medications, such as melatonin. However, if melatonin is not strong enough, you may require prescription sleep medications, such as trazodone.
While Fragile X Syndrome is not a life-threatening condition, it is a life-altering one. Your child will simply not develop and learn at the same rate as other children their age. As such, you, as the parents, may need counselling and support to cope with the anxiety and depression of raising a child with developmental difficulties.
However, while there is no cure for FXS, and it is a chronic genetic condition that will not resolve on its own, there are treatments that can mitigate the symptoms. As long as your child receives an early diagnosis of FXS and begins therapy and medications at the appropriate age, they can live mostly normal and healthy lives.
