Vitiligo reflects a systemic process that has important implications beyond the skin. These include other autoimmune diseases and ocular and neurological abnormalities.
So in the end that leaves no evidence that nerves are involved in vitiligo, at least for now. In summary, these observations make it pretty clear that vitiligo is an autoimmune disease that is initiated by melanocyte stress, which can be worsened by exposure to chemicals.
The most noticeable symptom is a rapid loss of vision. There may also be neurological signs such as severe headache, vertigo, nausea, and drowsiness. Loss of hearing, and loss of hair (alopecia) and skin color may occur along, with whitening (loss of pigmentation) of the hair and eyelashes (poliosis).
Vitiligo is caused by the lack of a pigment called melanin in the skin. Melanin is produced by skin cells called melanocytes, and it gives your skin its colour. In vitiligo, there are not enough working melanocytes to produce enough melanin in your skin. This causes white patches to develop on your skin or hair.
For every 100,000 person-years, 503 people with vitiligo developed dementia compared to just 102 healthy controls.
About 15 to 25 percent of people with vitiligo are also affected by at least one other autoimmune disorder, particularly autoimmune thyroid disease, rheumatoid arthritis, type 1 diabetes, psoriasis , pernicious anemia, Addison disease, systemic lupus erythematosus, celiac disease, Crohn disease, or ulcerative colitis.
Subsequent global studies have consistently reported the negative impact of vitiligo on patients' self-esteem and quality of life (QoL). Vitiligo causes isolation, stigmatization, loss of self-esteem, depression, and self-consciousness.
Stress increases the levels of catecholamines, neuropeptides, and cortisol that are higher in vitiligo patients [37–39] suggesting their role in the pathogenesis of vitiligo.
It's more visible in people with darker skin tones. Although vitiligo can develop in anyone at any age, macules or patches usually become apparent before age 30. You might be at a higher risk of developing vitiligo if you have certain autoimmune conditions like: Addison's disease.
Nevertheless, vitiligo has been found to be associated with chronic hepatitis C virus (HCV) infection and autoimmune hepatitis [17].
Vitiligo is a chronic (long-lasting) autoimmune disorder that causes patches of skin to lose pigment or color. This happens when melanocytes – skin cells that make pigment – are attacked and destroyed, causing the skin to turn a milky-white color.
Several studies showed that vitiligo has been associated with autoimmune thyroid diseases, pernicious anemia, Addison's disease.
Vitiligo is an autoimmune disease of the skin, which means that someone with vitiligo has an immune system that is malfunctioning in a small way. The normal role of the immune system is to protect you from infections and cancer.
Vitiligo does not pose a serious threat to one's health, but it can result in physical complications, such as eye issues, hearing problems, and sunburn. People with vitiligo also tend to be more likely to have another autoimmune disease (like thyroid disorders and some types of anemia).
The disease does not affect life expectancy. However, it can have a significant impact on quality of life, especially psychologically and be responsible for disorders such as depression and anxiety.
Vitiligo is an idiopathic disorder of skin and hair characterized by melanin loss. Nonetheless thyroid disorder is a major cause of this pathology, other factors participate in its expression. Hormones such as, testosterone and estrogen have been suspected as drivers of this disorder.
Research suggests that most people who develop vitiligo do so during childhood. As you age, Dr. Mohta says untreated vitiligo often progresses to involve the surrounding skin or create new patches of discoloration.
The condition usually begins with small white patches in a localized area. If the vitiligo progresses it can gradually spread across the body over time.
The one significant observation that we found to have the poor prognostic implication in vitiligo is the presence of mucosal vitiligo.
The triggers, which range from sunburn to mechanical trauma and chemical exposures, ultimately cause an autoimmune response that targets melanocytes, driving progressive skin depigmentation.
Skin lesions associated with vitamin B12 deficiency are skin hyperpigmentation, vitiligo, angular stomatitis, and hair changes. Cutaneous lesions that do not respond to conventional therapy can be an indication of vitamin B12 deficiency.
Vitiligo is epidemiologically associated with increased risk of autoimmune thyroid disease, type 1 diabetes, pernicious anemia, rheumatoid arthritis, systemic lupus erythematosus, and Addison's disease8,15.
As non-segmental vitiligo is closely associated with other autoimmune conditions, you may be assessed to see whether you have any symptoms that could suggest an autoimmune condition, such as: being tired and lacking energy (signs of Addison's disease) being thirsty and needing to urinate often (signs of diabetes)
Patients with vitiligo may be more likely to develop dementia than patients without vitiligo, according to findings from a retrospective cohort study published in the Journal of Dermatology. Vitiligo and dementia may be linked as they both involve autoimmune-related inflammation, it was posited.
