Altered Mentation: Anxious and Distressed States in Veterinary Patients
Altered mentation characterized by anxiety and distress is a non-specific clinical sign indicating potential neurological, metabolic, or systemic pathology. This article explores the diagnostic approach and differential considerations for various veterinary species.
Clinical summary
- Clinical signs
- Restlessness, pacing, vocalization, hyper-reactivity, defensive aggression, tachycardia, tachypnea, and diaphoresis (equine).
- Possible causes
- Primary causes include metabolic encephalopathies (hepatic, renal, hypoglycemic), toxicities (organophosphates, lead, tremorigenic mycotoxins), infectious etiologies (Rabies, Listeriosis in ruminants), and primary intracranial disease (trauma, neoplasia). Pain-induced distress is a frequent differential in all species.
- Diagnostic approach
- Requires a comprehensive physical and neurological examination. Diagnostic steps include minimum database (CBC/Biochem/UA), blood gas analysis, specific toxicology screens, and advanced imaging (MRI/CT) or CSF analysis if intracranial disease is suspected.
- Management
- Focuses on identifying and treating the underlying cause, stabilizing cardiopulmonary status, and providing symptomatic anxiolysis if safe (e.g., benzodiazepines or alpha-2 agonists, noting species sensitivities). Fluid resuscitation and glucose supplementation are critical first-line interventions in metabolic cases.
