Brief Summary
This study is a observational study conducted through recruiting X-linked adrenoleukodystrophy (X-ALD) patients, to build a comprehensive evaluation and long-term follow-up platform for X-ALD patients, and to provide a theoretical basis for the treatment and management of X-ALD patients.

Study Arms (2)
X-ALD
X-linked adrenoleukodystrophy (X-ALD) patients.
Carrier-control (CC)
Carriers of mutation in gene encoding ATP-binding cassette subfamily D member 1 (ABCD1), who have no X-linked adrenoleukodystrophy and are matched with the X-ALD group according to age, sex and education.
Eligibility Criteria
X-linked adrenoleukodystrophy patients, and age,sex and education matched healthy carriers will be recruited from the hospital.
You may qualify if:
- X-ALD group:
- Meet the diagnostic criteria of X-ALD and supported by the results of genetic and very long chain fatty acid (VLCFA) test;
- Age: 6 - 70 years old;
- Able to communicate normally, and complete the test of scale as instructed (confirmed by the field test of scale);
- Sign the informed consent.
- Carrier-control group:
- Healthy people who have no significant difference in age, sex and education comparing with the X-ALD group, volunteer to participate in this study, could complete the test of scale as instructed, and meet the following criteria:
- Eligible for asymptomatic carriers in genetic tests (preference of patient's mother and close relatives);
- Age: 6 - 70 years old, able to complete the test of scale as instructed (confirmed by the field test of scale);
- No history of psychiatric diseases.
You may not qualify if:
- Other hereditary diseases;
- Other severe central nervous diseases;
- History of surgery of brain or eye;
- Psychiatric and psychological diseases, such as anxiety and depression;
- Metal foreign body or prosthesis in the human body (such as pacemaker and insulin pump), claustrophobia, and other MRI contraindications;
- History of surgery associated with gastrointestinal tract;
- No informed consent;
- Unable to tolerate MRI or eye related tests.
