Progressive dementia

Treatment Options

Hematopoietic stem cell transplant
Gene therapy

Physical therapy
Speech therapy
Seizure management

Risk Factors

1X-linked inheritance
2Family history
3ABCD1 gene mutation
4Male sex

Diagnostic Methods

  • 1Plasma VLCFA levels
  • 2Genetic testing
  • 3MRI of brain
  • 4Adrenal function testing

Prognosis

Childhood cerebral form: fatal within 2-5 years without treatment. With early transplant, progression can be halted.

Prevention

  • Genetic counseling
  • Newborn screening
  • Family screening

Research Status

Hematopoietic stem cell transplant effective for early cerebral ALD. Gene therapy (eli-cel) FDA-approved. Lorenzo's oil may slow progression.
