Adrenoleukodystrophy (ALD) affects the myelin of the central nervous system. Symptoms can vary a great deal making diagnosis difficult but include weakness of muscle tone, aphasia, strabismus, hearing loss and worsening muscle weakness and leg stiffness.

The most common symptoms are behavioral problems and poor memory. Other symptoms frequently seen are loss of vision, seizures, poorly articulated speech, difficulty swallowing, deafness, problems with gait and.
The most severe form of adrenoleukodystrophy is known as cerebral adrenoleukodystrophy (CALD). This form primarily affects the brain and progresses rapidly, leading to severe neurological symptoms such as loss of cognitive function, movement disorders, and ultimately disability or death. Early detection and treatment are critical in managing CALD.

Adrenoleukodystrophy (ALD) is primarily caused by a mutation in the ABCD1 gene, which encodes a protein involved in the transport of very long-chain fatty acids (VLCFAs) into peroxisomes. This mutation typically results in a loss of function of the ABCD1 protein, leading to the accumulation of VLCFAs in the body. The genetic mutation is inherited in an X-linked recessive manner, meaning it predominantly affects males, while female carriers may exhibit milder symptoms.
Symptoms may include progressive stiffness, weakness, or paralysis of the lower limbs and loss of coordination. Brain function deterioration may also been seen. Women who are carriers of the disease occasionally experience the same.

Prognosis for childhood and neonatal ALD patients is poor because of the progressive myelin degeneration. Death usually occurs between one and ten years after onset of symptoms.
It was discovered by Haperfield and Spieler. ;)
That is the correct spelling of "adrenoleukodystrophy" (also called Siemerling-Creutzfeldt Disease and adrenomyeloneuropathy) a disorder affecting myelin sheaths in the nervous system.
10 billion percent!!
It is an X-linked recessive disorder.
