Dog Dementia: Understanding the Condition and Your Options

Dog dementia, also known as Canine Cognitive Dysfunction, is a common condition affecting older dogs. It's estimated that up to 80% of dogs over the age of 15 will develop some form of dementia.

As dogs age, their brains undergo natural changes that can lead to cognitive decline. Studies have shown that the brains of older dogs have reduced blood flow and decreased activity in areas responsible for memory and learning.

Dogs with dementia may exhibit changes in behavior, such as pacing, panting, and restlessness. They may also have trouble learning new things or recalling familiar commands.

Dog dementia, also known as canine cognitive dysfunction (CCD), is a cognitive disorder that affects the aging and functions of a dog's brain, causing effects similar to Alzheimer's disease.

Around 35% of dogs over the age of 8 may be affected by CCD, which is not a normal part of aging and does not occur in all dogs that live long lives.

CCD is similar to Alzheimer's disease in humans, and it occurs when amyloid plaques form in the front part of a dog's brain, creating cognitive difficulties.

Dogs with dementia usually have problems with memory and learning, and their personalities may alter as the disease progresses.

Here are the four types of cognitive syndromes that fall under the umbrella term of dog dementia or CCD:

Around one in three dogs aged 11 years or older display clinical signs of cognitive dysfunction, and nearly all dogs experience at least one symptom by the age of 16.

Dog dementia, also known as canine cognitive dysfunction, is a complex condition that affects our furry friends as they age. As dogs age, the brain atrophies, meaning that the cells die, especially in the portion of the brain responsible for learning and memory (the cerebral cortex) and the areas responsible for coordination (the cerebellum).

The exact causes of CCD are not known, but research has found that dogs with CCD have an abnormal protein (beta amyloid) building up in their brains, causing decreased nerve signaling. This protein buildup has also been linked to high levels of monoamine oxidase B (MAOB), which degrades neurotransmitters in the brain.

Dogs with epilepsy and those that lead a sedentary lifestyle are at a higher risk for developing CCD. Regular exercise, socializing, and minimizing stress can help reduce this risk.

Some of the key factors that contribute to CCD include:

By incorporating these preventative measures into your dog's life, you can help keep their brain healthy for longer.

Dog dementia can be a challenging condition to diagnose, as dogs can't verbally express their symptoms. Disorientation and confusion are common symptoms, and you may notice your dog looking lost in familiar surroundings or forgetting routines.

Disorientation can manifest in different ways, such as aimless wandering or staring. Your dog may forget their name, familiar people, or normal commands.

Changes in sleep patterns are another symptom of dog dementia. You may notice your dog sleeping a lot during the day and being up pacing, barking, or whining at night.

House soiling is a common sign of dog dementia, and it's often a result of your dog losing control of their bladder. Lack of activity and a decreased desire to play are also symptoms to watch out for.

Anxiety, lack of self-grooming, and a decrease in appetite can also be signs of dog dementia. Your vet will need to rule out other medical conditions before giving a definitive diagnosis.

Here are some common symptoms of dog dementia:

It's essential to recognize the symptoms of dog dementia early on, as it can progress gradually. Early signs include moments of disorientation, where dogs may seem lost or confused in familiar surroundings.

Diagnosis is a thorough process that involves gathering a detailed health history of your dog. This includes information about when symptoms first appeared and any relevant events.

Your veterinarian will conduct a comprehensive physical examination to assess your dog's overall health and cognitive function. Additional tests such as blood work, thyroid tests, ultrasounds, or X-rays may be suggested to rule out other potential causes of behavioral changes.

In some cases, advanced imaging like MRI or CT scans might be needed to confirm a diagnosis. Unlike humans, there isn't a specific test for diagnosing canine cognitive dysfunction syndrome (CDS), so your vet relies on a combination of symptoms, physical examination findings, and health history.

The cognitive assessment called DISHAA is used to evaluate six areas: Disorientation, Interaction, Sleep/wake cycles, House soiling, Activity, and Anxiety. This helps diagnose and indicate the severity of CCD that may be present.

Diagnosing dog dementia is a thorough process that requires your veterinarian to gather a detailed health history of your dog, including the onset and nature of symptoms. This information will help your vet rule out other diseases that may lead to behavioral changes associated with canine cognitive dysfunction syndrome.

Your vet will perform a complete physical examination to evaluate your dog's overall health status and cognitive functions. Routine blood tests, thyroid testing, ultrasounds, and X-rays are also employed to rule out other diseases.

There isn't a specific test for diagnosing canine cognitive dysfunction syndrome, so your vet will rely on a combination of symptoms, physical examination findings, and health history. Your vet will use a cognitive assessment called DISHAA in addition to asking you about your dog's behavior to make a diagnosis.

DISHAA evaluates six areas: Disorientation, Interaction, Sleep/wake cycles, House soiling, Activity, and Anxiety. Your vet will use bloodwork and diagnostic tests to rule out other health conditions that may be causing your dog's symptoms.

Your veterinarian may also recommend advanced imaging like an MRI or CT scan to verify a diagnosis of canine cognitive dysfunction. If your dog has canine cognitive dysfunction, they can begin treatment to help slow the progress of the disease.

Here are some treatment options you may want to discuss with your vet:

If your dog is experiencing cognitive decline, you may want to consider medication as an option. Selegiline, sold under the brand name Anipryl, is a prescription medication that can help treat symptoms of cognitive decline in dogs.

This medication is FDA-approved and has been shown to be effective in treating similar conditions in humans. It's essential to consult with your veterinarian to determine if medication is the right choice for your dog.

You can also help manage your dog's cognitive decline by making some lifestyle adjustments. For example, eliminating sources of stress can be beneficial, so try to avoid making any major changes around your home.

Keeping your dog's routine consistent can also help reduce confusion. This means keeping their bed and dishes in the same place, and avoiding taking them to unfamiliar places.

Giving your dog opportunities for mental stimulation, enrichment, and social interaction is also crucial. This can help keep them sharp and engaged, similar to how it benefits humans.

Life expectancy for dogs with dementia can be tricky to predict, as it's a degenerative process that occurs in a dog's senior years.

A dog's quality of life will eventually deteriorate due to dementia, but there's no specific timeframe established.

Working with your veterinarian to track your dog's quality of life is the best way to determine when it's time to consider their well-being.

You should talk to your vet about your dog's condition to get a better understanding of how far the disease has progressed.

A CCD assessment, like the one from Purina Institute, can inform you about the progression of the disease.

While dementia isn't curable, its progression may be slowed, especially if caught in the early stages.

Dog dementia progresses through three stages: early, where subtle changes occur, such as a dog becoming less social or waking up frequently in the middle of the night.

In the second stage, a dog may become disoriented or start eliminating in the house.

The final stage of dementia can be marked by aggression towards owners, not recognizing their name, or barking for no reason, in addition to worsening symptoms from the first two stages.
