More common signs and symptoms of alpha mannosidosis type 2 include:
Developmental delays (e.g., motor and speech)
Weakened immune system
Cerebellar disorders (e.g., ataxia)
Occasional psychiatric symptoms (e.g., depression, anxiety, or hallucinations)

Current treatment options for alpha mannosidosis may include bone marrow transplant or peripheral blood stem cell transplantation. Enzyme replacement therapy may be an additional treatment option in the future.
Treatments to address individual symptoms are recommended as needed, such as vaccinations, antibiotics, hearing aids, glasses, orthopedic and other assistive devices, educational interventions, and speech therapy. Regular follow-up to monitor health and treatment response is advised.
