A review of twenty longitudinal studies that examined cognitive outcomes in patients with epilepsy concluded that there is a ‘mild but definite’ relationship between seizures and mental decline [8]. Canine cognitive dysfunction; CCDR, Knowing what can trigger a seizure in your dog can often reduce their frequency. Or he’s something talking….but when I talk to him…it seems as if I’m a stranger…I’m not sure. They kept saying they thought it was a brain tumor and the only way they would know is a $2,500 MRI. Seizures, such as cluster seizures, grand mal seizures, and non-epileptic seizures, generally occur in a single part of the brain. It seems she still loves her walks and treats and gets excited when mommy comes home…but how will I know when it’s time? I am now wondering if our dog might have had Lyme also but he passed away before I became sick and learned about Lyme Disease. … Already available drugs may stave off and even reverse debilitating symptoms Yes MILES! If your dog is walking in circles, please see your vet right away. Are we missing a diagnosis based on outdated and improper assumptions? While epileptic seizures in dogs can happen for a variety of reasons – including ingesting poison – genetics can play a big role. Data are based on a generalised linear model with CCD as the binary outcome variable. She crossed the Rainbow Bridge today. So yesterday I held her and stared into eyes as she gently passed. But I hope those doubts are truly passing away because it’s clear you were an amazing guardian and friend to Princess. I appreciate your website and have found it to be very helpful. You can feel out of control and at a loss for how to help—and that’s only if you know one has even happened. There is debate as to whether cognitive impairments in epilepsy are (i) progressive, and as a result of the recurrent seizure activity that characterises epilepsy, (ii) static, and present from the onset of epilepsy, or (iii) due to other co-morbid neurological diseases. But after a few months, I realized that she was consistently drifting left and starting to circle. She never barks or cries. I apologize for my late response. New research from the University of Alberta shows that preventing seizures can delay or stop the onset of the dementia in people who have suffered a traumatic brain injury. Other pathological processes are likely to underlie these abnormalities. If you can time the length of the seizure, this will help. This is such a hard thing we sometimes have to do for our best friends. Eleven of the thirteen median scores for the subcomponents of the CCDR scale significantly differed between epilepsy and control dogs. Cognitive impairment was measured using the canine cognitive dysfunction rating scale (CCDR), a psychometrically validated tool that quantifies the frequency and progression of thirteen behaviours which, when abnormal, concur with veterinary diagnoses of canine dementia almost 80% of the time [34]. As dog owners, we are heavily burdened with the conscious and legal ability to humanely end a dog’s life. It is aweful to see our buddies go through that and not be able to fix them. She has loss vision her in her right eye almost 2 yrs ago. This may indicate that the cognitive problems in epilepsy evolves around the time of epilepsy onset or perhaps even earlier. All dogs go to heaven . In human neurology it is widely recognised that epilepsy is associated with cognitive impairment, with impaired cognition considered so prevalent that there are calls for repeated cognitive screening for all epilepsy patients [1]. Here we use data from a psychometrically validated tool, the canine cognitive dysfunction rating (CCDR) scale, to compare cognitive dysfunction in dogs diagnosed with idiopathic epilepsy (IE) with controls while accounting for age. She’s obviously gone stone deaf. This may indicate a bidirectional relationship between the disorders, such that dementia may precede or follow the development of epilepsy [20]. She actually began trying to climb through a 2 shelf side table, presumably to get to the other side? These findings may point towards an initial insult to cognitive function associated with epilepsy, rather than a progressive cognitive deterioration as classically seen in CCD in dogs and dementia in humans. It’s hard when their health declines in any way, but I think it’s especially hard on us when their bodies are healthy but their minds are affected. Roles Both girls are epileptic and one, we think, is completely blind now, she, Kara, is the one who is showing stringer signs of the condition. Phantom has weakness in his back legs which makes it difficult for him to stand for long periods and, once he’s down and then tries to get up, he has a difficult time especially since we have hardwood floors. Circling can be very obvious once the dog has an advanced case of dementia, but it doesn’t necessarily start out that way. Good comedians are equal opportunity insulters…). She actually has some anti-anxiety med here as needed, I’ve given her 1/2 dose twice in last two days. Thank you so so much for your post again . She has now gotten to the point that now that she cannot even walk or stand when I help her up. However, based on the current data, it appears likely that epilepsy-associated cognitive dysfunction represents a different form of cognitive impairment than the classic ‘canine dementia’ of CCD. I am so sorry for your loss. dog dementia seizures Fighting Canine Cognitive Dysfunction (Dementia) Jan 25, 2017 Health & Nutrition • Latest. Akaike information criterion; CCD, Hi Lynne, My adult Labrador can no longer walk the stairs above and down. This is, in part due to the formation of amyloid plaques within the brain. She also has reduced eyesight and is deaf. Epilepsy is an illness where seizures are the symptom of that illness. Model fit was checked by visually inspecting the distribution, and the homogeneity of variance, of the residuals, and the Akaike information criterion (AIC) values of each iteration. It is such a difficult decision. https://doi.org/10.1371/journal.pone.0192182.t001. Dogs who had experienced seizure activity, but whose owners only responded ‘yes’ to one or two of the above screening questions, were excluded from the study. Also, have you noticed that “doggie Alzheimer’s” is more prevalent in certain breeds? Shar Pei Recurrent Fever Syndrome. I’ve had to bring her to her dish for food and water. Most dementia dogs display some degree of stress, especially when lost in the corner of a room or if they find themselves awake and alone in the middle of the night. Of those dogs meeting tier I, 17% also achieved a atier II certainty diagnosis, as they had unremarkable fasting and post-prandial bile acids, magnetic resonance imaging of the brain and cerebrospinal fluid analysis [38]. It didn’t help, the symptoms progressed rapidly and it just got to where the only thing we COULD do for him was euthanization. This study provides initial evidence of increased levels of cognitive dysfunction in dogs with idiopathic epilepsy. From the current cross-sectional data, it remains unclear whether this effect in dogs is a reflection of (i) an underlying epilepsy phenotype characterised by degenerative cerebral processes that give rise to cognitive impairment and high seizure frequency, or (ii) progressive damage from recurrent seizures. broad scope, and wide readership – a perfect fit for your research every time. Globally, epilepsy is a common serious brain disorder. The studies say that there is not a particular breed that’s more vulnerable to it. What a blessing she has been…. When asked what he likes about it, he always says “They’re makin’ a left tuuuuuuuuurn! Guess I did not realize this was common…your dog is 19?! While we tend to associate them with convulsions, seizures can sometimes manifest with subtle symptoms, such as changes in behavior, movement, feelings, or levels of consciousness. For those answering yes, three further screening questions were posed: (i) whether their dog had 2 or more seizures that were at least 24 hours apart; (ii) whether their dog’s first seizure occurred between the ages of 6 months and 6 years; and (iii) whether their vet had carried out blood and urine tests on their dog and found no identifiable cause for their dog’s seizures. It sounds like you are a wonderful caregiver for your Heidi.This is a good place to talk about it; lots of people understand. Anxiety/restlessness. e0192182. Finally, it is possible that cognitive declines in adult and elderly patients with epilepsy are not solely a consequence of the seizure disorder. Investigation, Hi Eileen. So do Yorskhire terriers specifically. Yet, they gave me steriods and gabapentin to give her. Dog seizures can be terrifying for pet parents. Sydney School of Veterinary Science, Faculty of Science, The University of Sydney, New South Wales, Australia, Affiliation The vet is going to do blood tests but I am not sure if she can be helped or not. Over the last 2 years she has lost about 1/3 of her body weight and now has stabilized at 19 lbs. She takes 6 mil of insulin twice a day (shots). This article is written concerning DM, but it can be applied to a vast number of situations, illnesses and disorders, many neurological in nature such… However, no studies to date have identified this effect, and from these findings it appears that processes in the brain responsible for age-related behavioural changes may progress more rapidly in smaller dogs. A dog may have what is called focal or partial seizures. Two effects remained significant: IE and the interaction beween IE and age (Table 5). Globally, epilepsy is a common serious brain disorder. Dog Dementia or Canine Cognitive Dysfunction (CCD), an umbrella term for four separate cognitive forms, is an age-related neurobehavioral syndrome in dogs leading to a decline in cognitive function that can be devastating to the human/canine relationship. I’m sorry that I can’t really help you except to say that I know how hard it is when a dog has physical problems. Here is a short video of what it looked like. hippocampal volume), could provide evidence to test either hypothesis. (age unknown, rescue) Doberman girl who obviously has canine dementia. The possibility of a connection between life experience and the prevalence of dementia has long been discussed in human medicine, with the concept of “cognitive reserve” (CR) increasingly being investigated to account for individual differences in susceptibility to dementia or AD-related pathology [61]. It’s heartbreaking to say goodbye but good to know their souls are at peace. Almost three quarters of the sample were purebred (71.4%), over half of which were registered with a kennel club in their country (66.7%, n = 1923). Christy, I’m so sorry. Indeed, approximately half of newly diagnosed children or adults with epilepsy have demonstrable cognitive or behavioural difficulties on testing [12–14]. This study also identified age, size and training history as risk factors for CCD. There was no effect of any of these variables on CCDR score (p>0.05). Then I thought it was because her back legs were weak. My poor little old man. LOL. You can see that her left rear leg gets “left behind” but this was not diagnosed as a physical problem. These impairments may result from temporary disruption of neural activity patterns, and become permanent if seizures are more frequent [42]. © 2021 Dog Dementia Help and Support. I am grateful that so many people have gone and are going through the same thing. Finally, owners were asked to report what training aids and methods they used to train their dog. And yes, the most important thing is to get to the vet. The risk of CCD in healthy dogs increased exponentially with age beyond 10 years; however, risk of CCD in dogs with epilepsy was elevated at a comparatively young age (< 4 years) (Fig 1). Higher levels of training have been found to enhance peformance in dogs in various problem-solving tasks [57–59]. Although a screening tool for CCD (‘canine dementia’) was used to quantify cognitive abnormalities, the age of onset, nature and progression of cognitive impairment in dogs with epilepsy appears divergent from those seen in CCD. Seizures in the human temporal lobe (TLE) transiently impair cognition and steadily damage hippocampal circuitry, leading to progressive memory loss [9]. He has a brain tumor that we treated with radiation 2 and a half years ago, tumor reduced and is stabile but he had one isolated epileptic seizure a year ago. Blind in one eye and going there in the other. I’m SO glad I found your site. I hope your dog will do well. She even pulled consistently to the left when I walked her on leash.

A dog that has gone blind or deaf may appear to be less responsive to you and your family. With the exception of the amount of time spent physically active, dogs with IE did not show greater ‘progression’ of CCD signs than controls. On Wednesday I brought her to the vet as her one good eye which had diminished vision was weeping alot. To characterise the age of onset, nature and progression of any cognitive impairment observed in the population of dogs with IE; To identify disease and treatment-related risk factors for CCD within the population of dogs with IE; and. Dog dementia is more common than owners realize. A poor diet and inactivity can cause many issues in pets. When considering specific areas of cognitive compromise captured by the CCDR, dogs with IE showed significantly greater impairment in six of the seven ‘static’ elements, which chiefly reflect impairment in memory. Dear Betty, She is 14 and 1/2 years old and my vet thinks I should have her euthanized because the quality of her life isn’t good. We got him in to see our vet ASAP and he diagnosed Phantom as having a neurological disorder. It usually negatively affects the everyday life of a senior dog and … Long story short, he was going to end up at at Animal Control if no one took him. When I had him at the vet last week for his heartworm vaccination, his weight was down and I told the vet that I had started giving him more food because he was getting to be skin and bones from all the walking that he does. My boy, Phantom, had 2 seizures (that we know of) over a 2 or 3 month period. Circling behavior in dogs can be due to a variety of medical conditions, some of the immediately serious. Dogs that have more than one seizure in a 24-hour period are experiencing “cluster” seizures. In addition, clinicopathological studies are needed in dogs with IE to determine if, like in human epilepsy, they also express higher levels of Alzheimer pathology than normal. Responses were received from the owners of 4710 dogs, of which 4051 were eligible for inclusion. In control dogs, CCD prevalence was observed to increase with age, as has been previously documented, with peak prevalence observed in dogs aged >14 years old in both this study and a previous cross-sectional study [33]. Magnetic Resonance Imaging; SF, Cricket was doing it for several months before I noticed. You can feel out of control and at a loss for how to help—and that’s only if you know one has even happened. Take care. She has very bad back legs and often she’ll just poo anywhere if she can’t get up or if she gets excited, such as when I’m preparing her dinner. In this sub-population, dogs with epilepsy were at a significantly elevated risk of CCD than controls until around 7 years of age. Our vet has never mentioned medication for any of this, even though he’s aware of everything that’s happened. Thank you for extending love to Phantom even though he’s not a warm cuddly type. I noticed some time ago that she was having trouble getting around. Several factors predict reduced survival time in dogs with epilepsy, including poor seizure control and a high initial seizure frequency [50]. Causes of seizures can be divided by age group: Dogs Less Than Six Months. Her progression was pretty classic for cognitive dysfunction. Because of that and some other symptoms, she was diagnosed with canine cognitive dysfunction. I know she can’t be happy, she spends most of the day in my bathroom. He didn’t seem hurt orthopaedically but he was changed from the experience. Two weeks ago she started with the circling patterns, always to the left. I found out dogs can have it too.

The remainder were excluded due to a history of seizures without meeting diagnostic criteria for a Tier I level diagnosis, or due to being incomplete. Dog Seizure Causes and Diagnostics. He did not see an infection. Our vet has not encouraged us to use a medication, but I wonder if it might help, or have we waited too long? Age (years) was included as a variable in all models. Part of this early debate was further complicated by studies suggesting a slow cognitive decline with increased duration of epilepsy, but epilepsy duration is heavily confounded by ageing that is itself associated with cognitive decline. The low numbers in this sub-population limit our interpretation of the statistical models that compare geriatric dogs with epilepsy vs. controls in the age bracket for which CCD prevalence peaks in the control population. Figured her refusal to do tricks was a silent protest and her soiling everywhere was out of spite. In the final multivariate model, four variables remained significant: age, IE, bodyweight and training history (Table 4), with a significant interaction between age and IE diagnosis.
