Idiopathic Epilepsy
Idiopathic epilepsy
Tiež známe ako: Inherited epilepsy
Stručne
Idiopathic epilepsy is a common genetic seizure disorder in dogs and an uncommon one in cats. It is characterized by repeated seizure episodes with no identifiable underlying brain disease or metabolic cause, requiring careful diagnostic rule-outs and lifelong medical management.
TL;DR. Genetická záchvatová porucha: opakované záchvaty s normálnym zvieraťom medzi epizódami; diagnóza vylúčením a celoživotná liečba.
Medzi záchvatmi vyzerajú zvieratá zdravo.
Čo to je?
Idiopathic (inherited) epilepsy is recurrent unprovoked seizures with a normal brain between episodes. Neurons fire in a disorganized surge; no structural brain disease or metabolic toxin is found. Common in dogs; uncommon in cats. Diagnosis is by exclusion.
Príčiny a rizikové faktory
Presumed genetic. Distinct from reactive seizures (toxin/metabolic) and structural epilepsy. Onset typically young to middle-aged animals.
Príznaky
- Generalized tonic-clonic seizures (common)
- Focal seizures, cluster seizures (occasional)
- Status epilepticus: continuous seizure >5 min or no recovery between seizures (emergency)
Niektoré plemená majú mierne záchvaty s prikrčením a stuhnutosťou.
Diagnostika
Physical/neurologic exam between events. Bloodwork and glucose to exclude reactive causes; FeLV/FIV in cats. MRI and CSF when indicated. Diagnosis when extensive evaluation is normal.
Krvné testy vylúčia metabolické príčiny.
Liečba
Lifelong anticonvulsants: barbiturates, potassium bromide (generally avoid in cats), zonisamide, levetiracetam; second-line e.g. felbamate.
Prognóza
Many pets have good quality of life on therapy. Harder with early onset, large-breed cluster seizures.
Prevencia
Do not breed affected animals or close relatives in predisposed lines.
Kedy volať veterinára
Emergency: seizure >5 min, clusters within 24 h, failure to regain consciousness.
