Cerebelárna abiotrofia je degeneratívne ochorenie postihujúce mozoček, časť mozgu koňa zodpovedná za základnú rovnováhu a koordináciu. Tento stav sa všeobecne spája s čistokrvnými arabskými koňmi alebo s koňmi, ktoré majú arabskú krv.

V súčasnosti je o cerebrálnej abiotrofii známe len veľmi málo, hoci veterinári vedia, že toto ochorenie postihuje bunky v malom mozgu a spôsobuje stratu motorických funkcií a nekoordináciu u koní.

Príznaky

Cerebelárna abiotrofia najčastejšie postihuje žriebätá vo veku od jedného do šiestich mesiacov, aj keď ju možno príležitostne pozorovať u dospelých koní. Príznaky sa najskôr objavia mierne, zvyčajne ide len o miernu stratu rovnováhy. Veci sa potom budú postupne zhoršovať a chôdza koňa sa môže zvyšovať a spastickejšie; hlava môže dokonca klesnúť alebo prikývnuť.

Známky sú zvyčajne progresívne v priebehu niekoľkých mesiacov, ale potom stav prestane postupovať. Medzi ďalšie znaky, na ktoré si treba dávať pozor, patria:

• Škubanie
• Otrasy / chvenie
• Neprirodzená chôdza
• Kolaps
• Široký postoj
• Kôň môže pri zaskočení spadnúť

Príčiny

Cerebelárna abiotrofia je spôsobená predčasnou degeneráciou neurónov v malom mozgu. Strata týchto buniek ovplyvňuje rovnováhu a koordináciu koňa. Skutočná príčina tohto stavu nie je známa, aj keď sa predpokladá, že je genetická. Neboli zistené žiadne toxíny ani infekčné agens.

Diagnóza

Správanie spojené s počiatočnými štádiami cerebrálnej abiotrofie môže naznačovať ďalší stav alebo ochorenie, takže veterinárny lekár vykoná dôkladné fyzické a neurologické vyšetrenie. Iné laboratórne testy nie sú užitočné na diagnostiku tohto stavu, ale môžu sa použiť na vylúčenie iných príčin.

Liečba

V súčasnosti neexistuje žiadna liečba cerebrálnej abiotrofie, pretože mozgové bunky stratené touto chorobou nie je možné znovu získať. Zdá sa, že sa stav stabilizuje s pribúdajúcimi rokmi a uvádza sa, že niektoré kone sa časom mierne zlepšia.

Život a správa

Na koňovi, ktorý trpí cerebrálnou abiotrofiou, by sa nemalo vôbec jazdiť, pretože kvôli nedostatočnej koordinácii je jazda nebezpečná pre jazdca aj koňa. Mnoho koní s týmto ochorením je utratených, pretože sa stávajú nebezpečenstvom pre seba alebo pre ostatných.

Prevencia

Bohužiaľ v súčasnosti neexistujú žiadne preventívne opatrenia pre cerebrálnu abiotrofiu.
