The Krembil Research Institute, formerly known as the Toronto Western Research Institute, is an academic medical research institute in Toronto. It is one of the largest research institutes in Canada focusing on human neurological disease.
Krembil is one of the principal research institutes of the University Health Network and is the research institute of the Toronto Western Hospital.
Krembil researches treatments for Alzheimer's disease, Parkinson's disease, epilepsy, stroke, brain tumours, concussions, spinal cord injuries, neuro-ophthalmologic and other ocular disorders, multiple sclerosis and autoimmune disorders.
In the early 1980s, Toronto Western took on additional neurological and neurosurgical care responsibilities for the UHN group. In 1980, the Playfair Neuroscience Institute was created. In 1999, it was renamed the Toronto Western Research Institute. The Institute added research areas in ophthalmology, rheumatology and orthopaedics. By 2004, under the founding leadership of neurosurgeon C. Wallace, the Krembil had emerged as one of the largest research institutes in Canada with a neuroscience emphasis. [1]
On November 13, 2015, the Krembil took on its current name from the Krembil family. In 2013, the Krembil Discovery Tower opened at Toronto Western.
Krembil neuroscientists explore the function of the nervous system as they develop treatments for neurodegenerative diseases such as Alzheimer's disease and Parkinson's disease, epilepsy, spinal cord injuries, cerebral ischemia (stroke), vascular brain malformations, aneurysms, brain tumours and pain disorders.
The Krembil is also home to the Vision Science Research Program, a joint UHN/University of Toronto Program. This research is directed into the following areas: molecular genetics of blinding eye diseases with brain disorders; treatment and biophysics of glaucoma; eye movement control mechanisms; neuronal damage; retinal degeneration and diabetic retinopathy.
Arthritis and associated rheumatological degenerative diseases are the focus of the researchers in the musculoskeletal research program at the Krembil as part of the UHN Arthritis and Autoimmunity Research Centre. Their investigations are aimed at revealing the causes of, and generating therapies for, these autoimmune and orthopaedic ailments.[ citation needed ]
In September 2021, Krembil took ownership of the World Community Grid from IBM. [2]
Christopher Wallace MD, MSc, FRCSC, a neurosurgeon and neurophysiologist, was the first official director of the Krembil; his research focussed on therapeutic approaches to vascular brain injury. [1] Peter St George-Hyslop MD, PhD, FRCPC, a neurologist and PhD geneticist, was the second full-time director of the Krembil; his research focussed on the genetic basis of neurodegenerative diseases such as Alzheimer's dementia.

Krembil occupies 105,000 sq ft (9,800 m2) at Toronto Western Hospital for basic science, clinical, imaging and epidemiological research. In 2011, the Krembil was home to 122 biomedical researchers, 206 technical/support staff and 157 research trainees, who collectively produced 515 peer-reviewed publications supported by more than $43,612,000 of external research funding.
In 2013, Krembil expanded into an additional 325,000 sq ft (30,200 m2) of space, spanning nine floors, in the Krembil Discovery Tower. The Tower space includes 150,000 sq ft (14,000 m2) of "wet" laboratory bench space for Krembil basic science researchers.
Krembil receives support from the Toronto General/Toronto Western Hospital Foundation which is currently embarked upon a $200 million "Brain Campaign" to support neuroscience research at Krembil. The campaign had raised over $273 million as of January 2016.
The Krembil has many strategic research alliances, nationally and internationally, to facilitate and enhance the delivery of its research mandate. Two of the strategic research alliances are:
Dementia is a syndrome associated with many neurodegenerative diseases, characterized by a general decline in cognitive abilities that affects a person's ability to perform everyday activities. This typically involves problems with memory, thinking, behavior, and motor control. Aside from memory impairment and a disruption in thought patterns, the most common symptoms of dementia include emotional problems, difficulties with language, and decreased motivation. The symptoms may be described as occurring in a continuum over several stages. Dementia ultimately has a significant effect on the individual, their caregivers, and their social relationships in general. A diagnosis of dementia requires the observation of a change from a person's usual mental functioning and a greater cognitive decline than might be caused by the normal aging process.
Parkinsonism is a clinical syndrome characterized by tremor, bradykinesia, rigidity, and postural instability. Both hypokinetic as well as hyperkinetic features are displayed by Parkinsonism. These are the four motor symptoms found in Parkinson's disease (PD) – after which it is named – dementia with Lewy bodies (DLB), Parkinson's disease dementia (PDD), and many other conditions. This set of symptoms occurs in a wide range of conditions and may have many causes, including neurodegenerative conditions, drugs, toxins, metabolic diseases, and neurological conditions other than PD.
Apathy, also referred to as indifference, is a lack of feeling, emotion, interest, or concern about something. It is a state of indifference, or the suppression of emotions such as concern, excitement, motivation, or passion. An apathetic individual has an absence of interest in or concern about emotional, social, spiritual, philosophical, virtual, or physical life and the world. Apathy can also be defined as a person's lack of goal orientation. Apathy falls in the less extreme spectrum of diminished motivation, with abulia in the middle and akinetic mutism being more extreme than both apathy and abulia.
Progressive supranuclear palsy (PSP) is a late-onset neurodegenerative disease involving the gradual deterioration and death of specific volumes of the brain. The condition leads to symptoms including loss of balance, slowing of movement, difficulty moving the eyes, and cognitive impairment. PSP may be mistaken for other types of neurodegeneration such as Parkinson's disease, frontotemporal dementia and Alzheimer's disease. The cause of the condition is uncertain, but involves the accumulation of tau protein within the brain. Medications such as levodopa and amantadine may be useful in some cases.
Memory disorders are the result of damage to neuroanatomical structures that hinders the storage, retention and recollection of memories. Memory disorders can be progressive, including Alzheimer's disease, or they can be immediate including disorders resulting from head injury.
Pallidotomy is a neurosurgical procedure. It is used to treat Parkinson's disease and some other conditions, often as an alternative to deep brain stimulation. It involves placing a tiny electrical probe in the globus pallidus, one of the basal ganglia of the brain, to damage it. Unilateral pallidotomy can cause side effects including problems with language learning, visuospatial constructional ability, and executive functions. Bilateral pallidotomy is not effective, with many severe side effects.
Tauopathies are a class of neurodegenerative diseases characterized by the aggregation of abnormal tau protein. Hyperphosphorylation of tau proteins causes them to dissociate from microtubules and form insoluble aggregates called neurofibrillary tangles. Various neuropathologic phenotypes have been described based on the anatomical regions and cell types involved as well as the unique tau isoforms making up these deposits. The designation 'primary tauopathy' is assigned to disorders where the predominant feature is the deposition of tau protein. Alternatively, diseases exhibiting tau pathologies attributed to different and varied underlying causes are termed 'secondary tauopathies'. Some neuropathologic phenotypes involving tau protein are Alzheimer's disease, frontotemporal dementia, progressive supranuclear palsy, and corticobasal degeneration.
A neurodegenerative disease is caused by the progressive loss of neurons, in the process known as neurodegeneration. Neuronal damage may also ultimately result in their death. Neurodegenerative diseases include amyotrophic lateral sclerosis, multiple sclerosis, Parkinson's disease, Alzheimer's disease, Huntington's disease, multiple system atrophy, tauopathies, and prion diseases. Neurodegeneration can be found in the brain at many different levels of neuronal circuitry, ranging from molecular to systemic.Because there is no known way to reverse the progressive degeneration of neurons, these diseases are considered to be incurable; however research has shown that the two major contributing factors to neurodegeneration are oxidative stress and inflammation. Biomedical research has revealed many similarities between these diseases at the subcellular level, including atypical protein assemblies and induced cell death. These similarities suggest that therapeutic advances against one neurodegenerative disease might ameliorate other diseases as well.
Lytico-bodig (also Lytigo-bodig) disease, Guam disease, or amyotrophic lateral sclerosis-parkinsonism-dementia (ALS-PDC) is a neurodegenerative disease of uncertain etiology endemic to the Chamorro people of the island of Guam in Micronesia. Lytigo and bodig are Chamorro language words for two different manifestations of the same condition. ALS-PDC, a term coined by Asao Hirano and colleagues in 1961, reflects its resemblance to amyotrophic lateral sclerosis (ALS), Parkinson's disease, and Alzheimer's disease.

Alzheimer's disease (AD) is a neurodegenerative disease that usually starts slowly and progressively worsens, and is the cause of 60–70% of cases of dementia. The most common early symptom is difficulty in remembering recent events. As the disease advances, symptoms can include problems with language, disorientation, mood swings, loss of motivation, self-neglect, and behavioral issues. As a person's condition declines, they often withdraw from family and society. Gradually, bodily functions are lost, ultimately leading to death. Although the speed of progression can vary, the average life expectancy following diagnosis is three to twelve years.
Parkinson's disease (PD), or simply Parkinson's, is a neurodegenerative disease of mainly the central nervous system that affects both the motor and non-motor systems of the body. The symptoms usually emerge slowly, and, as the disease progresses, non-motor symptoms become more common. Usual symptoms include tremors, slowness of movement, rigidity, and difficulty with balance, collectively known as parkinsonism. Parkinson's disease dementia, falls and neuropsychiatric problems such as sleep abnormalities, psychosis, mood swings, or behavioral changes may also arise in advanced stages.
The neuroscience of aging is the study of the changes in the nervous system that occur with ageing. Aging is associated with many changes in the central nervous system, such as mild atrophy of the cortex that is considered non-pathological. Aging is also associated with many neurological and neurodegenerative disease such as amyotrophic lateral sclerosis, dementia, mild cognitive impairment, Parkinson's disease, and Creutzfeldt–Jakob disease.
