Dementia in dogs – when age takes its toll

Thanks to improved preventive care, senior dogs are no longer a rarity. Similar to humans, they suffer from classic age-related ailments such as osteoarthritis, cataracts, and dementia. Around 20% of nine-year-old dogs and almost 70% of 15-year-old dogs suffer from dementia, also known as canine cognitive dysfunction syndrome (CDS or "dog Alzheimer's").

Cause and origin

CDS is caused by changes in the nerve cells in the brain. The development of the disease is a complex interaction of many factors. Changes in brain metabolism and neurotransmitters lead to the development of CDS. Vascular changes, inflammation, and deposits of certain proteins also play a role. Risk factors include advanced age and idiopathic epilepsy (see corresponding article).

Symptoms

The initial signs are varied, which means that CDS is not always immediately recognizable. Dogs become disoriented and less lively than usual. They exhibit behavioral changes, become restless at night, and are no longer reliably house-trained.

The following symptoms may occur:

  • Disorientation
  • Changed social behavior: refusal of affection, reduced playfulness
  • Anxiety
  • Loss of house training
  • (Nocturnal) restlessness, constant compulsive wandering
  • Altered sleep-wake cycle
  • Behavioral changes: Yelping, aggression, biting
  • Forgetting commands
  • Reduced appetite
  • Staring into space

Especially at the onset of the disease, the signs are often dismissed as normal signs of aging. However, early detection is important, as progression can be slowed down by preventive and therapeutic measures.

Diagnosis

If you notice one or more of the symptoms described above in your dog, contact your veterinarian. However, the symptoms can also have other causes in older dogs. Therefore, your precise observations are important for making a diagnosis. A special questionnaire can indicate the presence of CDS. However, there are currently no specific tests to confirm suspected CDS. Other conditions such as osteoarthritis (see relevant article) or diabetes (see relevant article) must therefore be ruled out first.

Treatment

To date, CDS is incurable. However, special measures can be taken to alleviate the symptoms. Early diagnosis slows down the progression of the disease.

The following treatment options are available:

  • Mental training: Light command training, games, and activities keep your dog fit
  • Special foods with antioxidants
  • Pheromones and dietary supplements that have a calming effect
  • Medication that supports brain function

Since symptoms can vary from dog to dog, treatment is also individual. Your vet will discuss the options for your dog with you. They can send your dog's medication to petsXL digitally. This way, you can find all upcoming medication doses in your timeline and set reminders for yourself.

Forecast

To date, CDS is incurable. However, with appropriate treatment, your dog's quality of life will improve. The accompanying symptoms that make living together difficult, such as uncleanliness or restlessness at night, will also diminish.

Prophylaxis

Regular check-ups at your vet's practice provide an opportunity to assess your dog's general state of health. Particular attention should be paid to possible symptoms that indicate CDS, especially in older dogs. A special questionnaire may be useful for this purpose.
