LMNB1-related autosomal dominant leukodystrophy (ADLD) should be suspected in adults with the following clinical, neuroimaging, and family history findings:
Clinical features
Onset in the fourth to fifth decade of signs and symptoms of autonomic dysfunction including bladder dysfunction, constipation, erectile dysfunction, and postural hypotension
No approved treatments are currently available for leukodystrophy, demyelinating, adult-onset, autosomal dominant, typical. The disease remains an area of unmet medical need.
No clinical practice guidelines for LMNB1-related autosomal dominant leukodystrophy (ADLD) have been published. Evaluations Following Initial Diagnosis To establish the extent of disease and needs in an individual diagnosed with LMNB1-related ADLD, the evaluations summarized (if not performed as part of the evaluation that led to the diagnosis) are recommended. Table 3. Recommended Evaluations Following Initial Diagnosis in Individuals with LMNB1-related Autosomal Dominant Leukodystrophy (ADLD)
Recommended surveillance:
Routine assessment of weight, nutrition, and feeding; pulmonary status (re possible recurrent pneumonia); bladder and erectile function; psychosocial well-being; and medications and dosage to avoid iatrogenic polypharmacy
At least annual assessment by multidisciplinary specialists including a neurologist for disease manifestations and progression; and by a physiatrist, orthopedist, physical therapist, and occupational therapist to address orthopedic, equipment, and functional needs
No clinical trials have been registered for leukodystrophy, demyelinating, adult-onset, autosomal dominant, typical.
5 publications have been identified in PubMed for leukodystrophy, demyelinating, adult-onset, autosomal dominant, typical. Research spans Basic Science / Preclinical (40%), Review / Meta-Analysis (20%), and Case Report / Case Series (20%).

LMNB1-related autosomal dominant leukodystrophy (ADLD) is a slowly progressive neurologic disorder of central nervous system white matter. Adults show autonomic dysfunction, the first evidence of the disorder, in the fourth to fifth decade of life, followed by pyramidal and cerebellar abnormalities resulting in spasticity, ataxia, and tremor . To date, at least 33 families have been identified with a pathogenic variant in LMNB1 [, , , , , , , , , , , , , , ]. The following description of the phenotypic features associated with this condition is based on these reports. Autonomic dysfunction, a nearly universal feature , includes bladder dysfunction, constipation, postural hypotension, erectile dysfunction, and (less often) impaired sweating.

Subsequent onset of motor and cerebellar impairment resulting in spasticity, ataxia, and tremor
MRI findings. Brain and spinal cord MRI findings can precede clinical manifestations by decades. Specific brain and spine MRI findings suggestive of LMNB1-related ADLD [, , , )] include the following:

The differential diagnosis of LMNB1-related autosomal dominant leukodystrophy (ADLD) includes other leukodystrophies with adult onset as well as acquired demyelinating disorders such as multiple sclerosis.
Multiple sclerosis (MS) is an inflammatory disease that affects central nervous system white matter. The age of presentation and combination of motor, cerebellar, and autonomic manifestations make this disorder in some instances similar to LMNB1-related ADLD . Unlike the brain MRI in LMNB1-related ADLD, the brain MRI in MS is characterized by multifocal lesions mainly around the periventricular area, brain stem, cerebellum, and spinal cord . CSF contains high IgG and oligoclonal bands .

Because disease manifestations may be exacerbated with fever and infection, care should be taken to avoid whenever possible exposure to those with infections.
