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.

FUNDRAISING - Award-winning Linos Trio supports NA with London concert
Join us in London November 10th, a highlight for NA Fundraising in 2014, with a concert featuring the award-winning Linos Trio. With Prach Boondiskulchok (piano), Konrad Elias-Trostmann (violin) and Vladimir Waltham (cello), this is not an event to be missed. The programme features C.P.E.Bach's Piano Trio in G Major Wq.90 no. 2, Schumann Trio in G Minor, Op.110 and Beethovan's Piano Trio, Op.97 'Archduke'. Konrad, Vladimir and Prach share five nationalities, matched by the similarly wide range of their musical backgrounds, which include historically informed performance practice, composing and improvising. All of this is brought together to support a dynamic and refreshing vision of making music.
“The players brought brilliance and élan [to the work] . . . performed with control and tonal intensity . . . the ensemble between these three players was superb . . . Their winning way with slow sustained lines . . . This was a slow-burning, gripping performance, the playing rich and passionate” - The Strad.
The Advocacy is grateful to Vernon and Hazel Ellis for presenting this programme to support patients and families and to contribute to research. A silent auction and raffle will be included on the evening. 7 for 7.30 pm at 49 Queen's Gate Terrace, London SW7 5PN. Voluntary donation of £35 to include wine, canapés & supper. Cheques payable to NA Fund. To reserve a place email Vernon@vef.org.uk.
