:: How to recognise Neurocanthocytosis

The first signs of the diseases in the neuroacanthocytosis (NA) group are subtle and easily overlooked. Initial symptoms, which often occur in the person’s mid 20’s, may include grunts or tic noises made unconsciously in the throat, progressing to drooling and problems in controlling the tongue from ejecting food. Involuntary biting of the tongue, lips and/or cheeks may follow.

At the beginning there can be a general, slight physical awkwardness. Things on a shelf are knocked off for no apparent reason. Difficulty with walking and balance can also be early symptoms. Problems controlling trunk, leg and arm movements are often barely noticeable at the beginning, but become increasingly difficult as the disease progresses. Several patients find it difficult to sleep at night and others report fatigue and weakness.

Personality change may also be an early indication. The carefree young adult becomes obsessive-compulsive and uncharacteristically forgetful or just loses confidence or drive. Fainting or epileptic seizures may also occur. Mood changes may happen and a person often becomes isolated, in part out of embarrassment.

There are several reports of the problems beginning after a traumatic event including physical attack, unexpected failure of an exam and birth of a child.

CLINICAL SIGNS

A defining symptom that is not apparent is the spiky red blood cells, or acanthocytes, from which the NA disease group takes its name. These unusual blood cells can be observed with a microscope in some circumstances. Still more difficult to observe are the alterations or mutations in patients’ genes. Each of the NA group diseases has a different genetic characteristic that can be determined only by blood tests.

A person showing some of this pattern of symptoms should see a neurologist. Clinicians and patients can also visit www.naadvocacy.org for links to further scientific reports. Full details are also available on the free blood testing service offered by the Advocacy for Neuroacanthocytosis Patients, aimed at helping determine a definitive diagnosis for NA.

Pete Clark's latest news

Pete Clark writes with his news: "I moved into my own flat nearly 18 months ago it’s in a warden controlled complex of 15 flats where I have carers coming in twice a day and an alarm system I can use to call for help in an emergency 24 hours a day. At first I found the situation quite daunting and to be honest at times I felt a bit overwhelmed. Now I’m feeling much more settled and enjoying myself.

Pete Clark's latest news

"Being part of the Southend Branch of the Huntington’s Disease Association has improved my quality of life enormously. On Wednesdays I go to the group’s allotment where my nickname is ‘Parsnip Pete’ (after a somewhat disasterous attempt at growing parsnips). There is a wonderful atmosphere and we have lots of fun...and endless cups of tea. The group has its meetings on a Thursday, where after news updates tea and cake there is opportunity to take part in exercises, followed by relaxation. Occasionaly there are events at the allotment such as mayday celebrations and day trips. Often I get inspiration from these to write poems that are then read out to the group (not by me as the quality of my speech is generally poor. In fact just a few months ago I received from my speech therapist, an iPad with text to speech software. I think this is going to be very useful as a back up, but I’m going to try not to rely on it.)

"I have also made a good friend at the Huntington group with similar taste in music and we have been to several concerts together. Last month we went on an amazing trip – a flight to see the Northern Lights, something I’d wanted to do for a long long time. Thanks to mum for making it possible."
