Diagnosis
The following diagnostic methods can be used to diagnose Wolfram-like syndrome

Genetic mutation responsible for Wolfram-like syndrome
Genetic testingWhole exome sequencing
Whole genome sequencing
Gene sequencing focused on the WFS1 gene

Diabetes
Blood testsBlood sugar test at a random time
Fasting blood sugar test
A1C test
Oral glucose tolerance testing

Hearing loss
At-homeHearing loss screening mobile apps
Whisper test
In clinical settingAudiometer tests
Tuning fork test
Physical examination

Optic atrophy
OphthalmoscopyOptic disc examination, paleness strongly indicates optic atrophy
Visual acuity examination

Psychiatric symptoms
Depression
Use of the DSM-5 depression diagnosis criteria
Physical examination
Laboratory studies
Psychiatric evaluation

Anxiety
Use of the DSM-5 criteria for anxiety disorder
Psychological evaluation

Hallucinations (with or without delusions and/or disconnection from reality)
Hallucinations dont necessarily need to have an official clinical diagnosis (although one can be useful for treatment to be performed), but it can be used as a diagnostic method for other conditions such as psychosis or schizophrenia. Hallucinations can be auditory, visual, tactile, olfactory, or gustatory, and they involve a false perception of stimuli where there is none. The same (no necessary need for official clinical diagnosis but can be used as a diagnostic method for other conditions) goes for delusions, there are various types of delusions, including somatic, persecutory/paranoid, grandiose, etc. They involve a false, fixed, often irrational belief a person fully believes in and is hard to convince out of. Treatment
There is no standard management method for Wolfram-like syndrome, however, the following treatment methods can be used to treat the symptoms Wolfram-like syndrome causes. Diabetes
Insulin intake
Regular blood sugar monitoring
The use of metformin medication
Healthy eating habits
Regular physical activity

Hearing loss
Hearing aids
Cochlear implants
Surgical procedures

Vision loss
Optical aids
Surgical procedures
Medication

Psychiatric symptoms
Therapy (for depression, anxiety, etc.) Use of medication (antidepressants, antipsychotics, etc.)
Wolfram-like syndrome is a rare autosomal dominant genetic disorder which shares some of the features shown by those affected with the autosomal recessive Wolfram syndrome. It is a type of WFS1-related disorder. Signs and symptoms
Individuals with this condition usually exhibit early-onset progressive hearing loss which starts around the age of 10 years old, early-onset optic atrophy which usually manifests in a persons mid teenage–late adulthood years of life, and adult-onset diabetes mellitus.Although rarely, psychiatric symptoms can also manifest in people with the condition, this group of symptoms consists of hallucinations, depression, anxiety, and sleep disorders.Psychosis and autism are sometimes seen as features of the disorder.Other symptoms include nephrocalcinosis, psychomotor delay, glaucoma, and megalocornea. Complications
The psychiatric features that may appear in patients with this condition, particularly depression, can cause a patient to be live in a constantly miserable state of mind, which can lead some patients to develop suicidal tendencies and, which can ultimately lead to making the decision of commiting suicide.
