The best way to treat ATM gene mutations is to focus on the specific symptoms they cause. Depending on the type of mutation present, treatment may involve using medications, physical therapy, occupational therapy, or even surgery. Medications may be used to reduce pain, swelling, or other symptoms. Physical therapy can help improve strength, mobility, and overall physical functioning. Occupational therapy can help improve daily functioning, including activities of daily living, such as dressing, eating, and bathing. Surgery may be needed to correct certain structural abnormalities caused by mutations. Ultimately, the best approach is to work with a team of healthcare providers to determine the best treatment plan for the individual.
