Causes
CognitiveCognitive refers to the mental processes of recognizing, thinking, learning, and understanding. Cognitive functions in dogs and cats include memory, perception, problem-solving, and decision-making. Cognitive dysfunction can occur in older animals and is similar to dementia in humans. dysfunctionDysfunction refers to an impaired or abnormal function of an organ or system in the body. This can be due to diseases, disorders, or damage and can affect the quality of life. in dogs is a complex neurodegenerative process that mirrors the aging process of the brain. Similar to Alzheimer’s disease in humans, there is an accumulation of beta-amyloid proteins that form plaquesPlaques are deposits or accumulations of substances on the inner or outer surfaces of body tissues. In veterinary medicine, they can occur on the skin, in blood vessels, or in the brain. and disrupt neuronal communication. These plaquesPlaques are deposits or accumulations of substances on the inner or outer surfaces of body tissues. In veterinary medicine, they can occur on the skin, in blood vessels, or in the brain. impair the function of nerve cells and ultimately lead to their death.
Further scientific findings show that oxidative damage and reduced neurotransmitterNeurotransmitters are chemical messengers that transmit signals from one neuron to the next across the synaptic cleft. They are essential for numerous functions of the nervous system, including mood, sleep, and motor skills. activity may also play a role. These changes lead to a reduced ability of the brain to process and retrieve information, which manifests itself in memory-related deficits.
The exact causes are not yet fully understood, but it is believed that genetic factors, nutrition, environment, and the general health of a dog may also play a role. Some breeds appear to be more susceptible to developing DementiaDementia is an umbrella term for diseases characterized by a progressive loss of cognitive function, severe enough to interfere with daily life. Alzheimer's disease is the most common form of dementia. due to genetic predispositionA predisposition is an innate inclination or susceptibility of an organism to certain diseases or conditions. In dogs and cats, there may be a genetic predisposition to certain conditions such as hip dysplasia or certain heart diseases..
Hormonal changes and a disturbed sleep-wake cycle could also influence the development and course of the disease. Since dogs have a shorter lifespan than humans, the aging process progresses more rapidly, which increases the likelihood that DementiaDementia is an umbrella term for diseases characterized by a progressive loss of cognitive function, severe enough to interfere with daily life.
