The dementia that can be cured
There are more than 200 subtypes of dementia. And researchers have found that in one, confusion and memory loss can be treated. But the trick is to spot it…

Dementia is not just one disease – it has more than 200 different subtypes. Over the past decade neurologists have become increasingly interested in one particular subtype, known as autoimmune dementia. In this condition, the symptoms of memory loss and confusion are the result of brain inflammation caused by rogue antibodies – known as autoantibodies – binding to the neuronal tissue, rather than an underlying neurodegenerative disease. Crucially this means that unlike almost all other forms of dementia, in some cases it can be cured, andspecialist neurologists have become increasingly adept at both spotting and treating it.

But autoimmune dementia is also an illustration of a broader trend. Over the past 15 years, treatable diseases have been identified across an entire spectrum of neurological illnesses from epilepsy to multiple sclerosis and psychiatry, all caused by autoantibodies binding to different parts of the brain and central nervous system.

Since 2004, scientists have been steadily discovering the autoantibodies behind these various neurological conditions, making it possible for clinics to test for them. Irani says that so far they have discovered approximately 25, with one or two new autoantibodies detected every year.
Treatments mentioned include steroids, rituximab and plasma exchange.
