Dementia in dogs
Senile dementia in dogs is a serious disease and should not be confused with normal senility. The technical term for this disease is Cognitive Dysfunction Syndrome (KDS) and is currently often underdiagnosed.
But why does it matter, and why is it important to know?
Because we can do something about it. The quality of life of your senior pelt-nose can be noticeably improved, with the aim of keeping the relationship with your faithful companion as normal as possible for as long as possible. It is our concern to make a contribution to this and to support you in doing so.
Several studies have shown that one in three dogs between the ages of eleven and twelve and up to one in two dogs aged 15 and over can be affected by senile dementia. In a particularly rapid progression, the first signs can appear as early as six years of age.
Cognitive dysfunction syndrome is an incurable, progressive, neurodegenerative disease. Neurodegeneration can be thought of as a change in brain structures with atrophy of nerve cells and thus a loss of normal brain function. The brain structure is altered by deposits of various proteins. These include beta-amyloid plaques and the pigment lipofuscin. There is evidence of inflammation and increased release of free radicals, which in turn can lead to damage and progressive degeneration of brain tissue. Brain tissue is particularly susceptible to free radical damage. In addition, the altered brain structures lead to an imbalance between the neurotransmitters that are responsible for normal behaviour in everyday life. With the described changes in the brain, the disease strongly resembles Alzheimer's disease in humans.
We are therefore talking about a progressive brain disease that leads to a gradual decrease in cognitive ability. Early detection is an important element in preventing rapid progression.
Early detection gives us the opportunity to use targeted training, nutritional supplementation and medication to slow down the progression of the disease, if not stop it, at least significantly and improve quality of life.
How can we recognise cognitive dysfunction syndrome? What is meant by altered cognitive abilities?
When we talk about cognitive abilities, we mean the attention, conscious awareness, memory and learning abilities that an individual brings to the table. Changes in cognitive abilities may announce themselves as follows: Disorientation / confusion
The animals want to do something and suddenly seem to forget what it was. For example, they want to go into the garden, then stand outside and pause as if they have forgotten what they were about to do. Or monotonous walking around, sometimes with monotonous vocalising, or staring into corners can be observed.
Altered social interaction with people or other animals
Familiar people and animals may no longer be recognised or an unfamiliar greeting may be given. When called, they may look in the wrong direction and have difficulty finding their owner on the walk.

Change in sleep/wake cycle
Normally, dogs sleep through the night, much like their owners, with extra rest during the day. In sick dogs, this behaviour can change. They sleep more during the day and have more periods of wakefulness at night, up to and including prolonged periods of insomnia. Sudden startling from sleep and restless sleep may also occur.
Unlearning what has been learned
Basically, a reduced ability to learn and forgetting of what has been learned can be noticed. This can go so far that even house-training is no longer possible. Known commands are forgotten, or there is a longer reaction and execution of the command. We must not confuse this with "stubbornness in old age" or reduced hearing ability.
Altered activity
Initially, increased sleep and reduced interest in social activity may be observed, followed by increased restlessness, restlessness and night waking or other repetitive behaviour patterns.
In addition, anxiety disorders such as separation anxiety, sound phobias (thunderstorms/thunder), increased barking, reduced grooming and altered appetite may occur.
Important to know
We must be aware that there is no cure for KDS. The course of the disease is influenced by various factors. Accordingly, there are also different therapy approaches that are in focus. Basically, as in humans, the earlier the therapy is started, the slower the progression of the disease. We can therefore support your dog with the appropriate therapy and thus slow down the course of the disease.
However, the first step is always to check or clarify other medical conditions that may cause similar symptoms. It is also known that dental diseases as well as joint diseases can promote dementia.
How can your dog be helped?
The selection of the appropriate therapeutic treatment depends on the individual needs of our patients and should be chosen carefully. We focus on the following therapeutic approaches:
-Assistance in everyday life
-Adherence to a constant, regular daily structure
-Mental / cognitive stimulation: regular practice of commands, playing, adding new toys, searching games, chewing toys
-Increased / regular activity: Increased short walks to clean up can help maintain housetraining. Dietary measures
Various scientific studies have shown that specific dietary measures as well as food supplements can provide support. These include vitamins B, C and E, beta-carotene, selenium, mitochondrial co-factors (alpha-lipoic acid and L-carnitine), and essential fatty acids (MCT, omega-3 fatty acids / DHA).
Medication
In certain patients, it may be useful to support the therapeutic measures with additional medication. For animals that are very anxious or show significant nocturnal activity, antidepressants or anti-anxiety medication may be used.
Dementia neurology consultation as an exclusive offer
KDS is an under-diagnosed disease of our senior cats. The first signs of the disease as well as the individual course can vary greatly. Making a diagnosis can seem difficult at first glance because it is a complex clinical picture. It is our goal to diagnose affected patients at an early stage and thus be able to initiate therapy in time. In this way, we can help to improve your pet's quality of life in old age and maintain it for as long as possible.
In the specialist clinic of the Veterinary Clinic Basel, we offer a wide range of neurological services in the department of neurology exclusively in the Basel area, in order to detect neurological diseases early, to clarify them in a problem-oriented manner and to treat them in a targeted manner.

We offer special dementia consultation hours for the diagnosis and treatment of cognitive dysfunction syndrome in dogs.
We cover the following services:
- Early detection and diagnosis of Cognitive Dysfunction Syndrome.
- Counselling and discussion of preventive measures
- Exclusion of other diseases by means of specialised diagnostics
- Preparation of an individual therapy plan for animals suffering from Cognitive Dysfunction Syndrome
In cooperation with our specialist clinic (surgery, internal medicine / cardiology, radiology, dentistry, sports and pain) we can ensure a multimodal improvement in quality of life
We work closely with your family veterinarians to provide optimal care in the longer term
We offer the opportunity to participate in our special training sessions in the "Memory Gym" to improve the mental and motor skills of older animals. More At:
