Anxiolytics and Antidepressants Alterations in neurotransmission can lead to irrita- bility, decreased responsiveness to stimuli, fear, and agitation. Antidepressants and anxiolytics may be considered in some older pets. These include clomi- pramin, amitriptyline, fluoxetine, and paroxetine ben- zodiazepines and buspirone. Cholinergic function in the brain is important for memory and older dogs show a greater sensitivity to cholinergic disruption which impairs working mem- ory. Clomipramine, paroxetine and amitryptiline are anticholinergic and should be used with care - drugs selected should enhance and not reduce neuronal cholinergic activity if possible. 0.5 – 1.5 mg/kg oid 0.5 – 1 mg bid Not determined 2.5 mg/kg bid 5 – 10mg/kg oid -tid Not recommended 0.5 – 1 mg/kg oid in am Not determined 3mg/kg per os oid Table 4: Drug Doses for Behaviour Therapy Diet Dietary strategies involve supplementation with anti oxidants and mitochondrial co-factors to improve anti oxidant defences as well as reduce production of, toxic effects of, and increased clearance of oxy- gen free radicals. Vitamins E and C, beta-carotene, selenium, and other flavonoids and carotenoids from fruits and vegetables have antioxidant and anti-in- flammatory properties in the treatment of cognitive dysfunction. B vitamins (thiamine, ri boflavin, niacin B6 and B12) may also have antioxidant and neuropro- tective effects as well as the ability to normalise neu- rotransmitter levels. Enhancement of mitochondrial function is achieved with the addition of L-carnitine and DL-alpha-lipoic acid. The efficacy of Hills B/D TM has been evaluated over a trial period of 2 years using neurophsychological testing well as in clinical trials and was found to im- Issue 06 | DECEMBER 2017 | 37
