11 Unmistakable Signs You Might Be Dealing with Smith-Magenis Syndrome

5. Frequent Temper Tantrums And Aggression

Behavioral abnormalities, such as frequent temper tantrums and aggression, may manifest in Smith-Magenis syndrome patients. It is thought the temper tantrums and aggression are reactions to situations where patients feel they are not receiving enough attention from a particular person or group. Children exhibit these behaviors more often than adults with Smith-Magenis syndrome, and the aggression is often directed toward their caregiver or another adult with whom they have a close connection. Aggressive behaviors commonly seen in affected individuals include many forms of self-injury that are repetitive, like hitting, picking the skin, banging the head, grinding of the teeth, insertion of hands or objects in the mouth, and biting. Abnormal impulsiveness, anger or frustration outbursts, excessive anxiety, and problems with focus and concentration are other behavioral problems that frequently manifest in Smith-Magenis syndrome patients.

6. Unusual Sensory Processing

Many individuals with Smith-Magenis syndrome experience heightened or diminished sensitivity to sensory input. They might become overwhelmed by loud noises, bright lights, or certain textures, while others seek out intense sensory experiences, such as spinning, deep pressure, or repetitive movement. This atypical sensory processing can result in either avoidance or sensory-seeking behaviors that may confuse those unfamiliar with the condition. A child may insist on wearing tight clothing for comfort or become distressed by minor environmental sounds. Understanding and managing these sensory sensitivities can greatly improve the individual’s daily functioning and emotional regulation, especially in educational or social settings.
