Multiple sclerosis (MS) can often be a hard disease to diagnose, chief executive of the MS Trust Pam Macfarlane has said.
She stated some common symptoms of the illness include burning sensations, pins and needles, balance and mobility problems, numbness, fatigue and the loss of vision in one eye.
However, "the symptoms are very varied and can be common to many other conditions", the expert remarked.
Among young adults, MS is the most common disease to strike the central nervous system, Ms Macfarlane added.
Women are more at-risk of the condition than men are and it is usually diagnosed when a sufferer is in their 20s or 30s, she noted.
Recently, Jack Osborne, the son of Black Sabbath frontman Ozzy Osborne, was diagnosed with MS.
