Summary
The World Health Organisation Disability Assessment Schedule II (WHODAS II) is a reliable and valid tool for assessing stroke patients' disability in the first year post-stroke.
Area of Science:
- Rehabilitation Medicine
- Neurology
- Health Outcomes Research
Background:
- Stroke is a leading cause of long-term disability.
- Accurate assessment of disability is crucial for effective stroke rehabilitation and patient management.
Purpose of the Study:
- To evaluate the internal consistency, inter-rater reliability, and validity of the World Health Organisation Disability Assessment Schedule II (WHODAS II).
- To assess the suitability of WHODAS II for use in stroke patients and their caregivers.
Main Methods:
- Self- and proxy-rating versions of WHODAS II were administered to stroke patients at 6 months and 1 year post-stroke.
- Validity was assessed using the modified Rankin Scale (mRS) and patient self-reports on recovery and independence.
- Patient-reported restrictions and limitations were compared with WHODAS II items.
Main Results:
- WHODAS II demonstrated good to excellent internal consistency and satisfactory to good inter-rater reliability.
- Item reliability varied from insufficient to good, with agreement percentages below 80%.
- WHODAS II scores significantly differentiated between patients with different mRS scores and self-reported recovery/independence levels, showing fair to high correlations with validation measures.
Conclusions:
- The WHODAS II is a valid and generally reliable instrument for assessing stroke patients within the first year after stroke.
- It serves as a useful tool for evaluating disability and guiding rehabilitation efforts in the post-stroke period.

01:17Hemorrhagic Stroke l: Introduction
A hemorrhagic stroke is an acute neurological event that occurs when a weakened cerebral blood vessel ruptures, allowing blood to accumulate within or around the brain. The sudden release of blood forms a focal hematoma that increases intracranial pressure, displaces neural tissue, and can obstruct cerebrospinal fluid pathways. These effects may be compounded by intraventricular extension of the hemorrhage, cerebral edema, or compression of adjacent structures, all of which contribute to...
01:15Ischemic Stroke l: Introduction
Ischemic stroke is an acute cerebrovascular condition in which blood flow to a brain region is suddenly interrupted, leading to tissue infarction. Neurons depend on continuous oxygen and glucose supply, so even brief reductions in perfusion cause energy failure, ionic imbalance, and irreversible injury. Ischemic strokes are classified into thrombotic and embolic types based on their underlying mechanisms.Thrombotic MechanismsThrombotic stroke develops when a clot forms within a cerebral artery.
01:30Dementia
Dementia is a collective term for cognitive disorders primarily affecting memory, thinking, and reasoning. It is not a specific disease but a syndrome, with Alzheimer's disease being the most common cause, accounting for approximately 60-80% of cases. Other types include vascular dementia, Lewy body dementia, and frontotemporal dementia. Dementia affects millions worldwide, particularly older adults, though it is not a normal part of aging.
The progression of dementia is generally gradual.

01:28Traumatic Brain Injury l: Introduction
DefinitionTraumatic brain injury, or TBI, is a disturbance of normal brain function induced by an external mechanical force, such as a direct blow to the head or a penetrating injury. It can affect both brain structure and function, producing a wide range of clinical outcomes. TBI is a heterogeneous condition, meaning its effects may differ based on the type, location, and severity of the injury.Basis of ClassificationTBI is classified based on severity, injury mechanism, or pathophysiology. In...
01:22Dementia l: Introduction
Dementia is an acquired, progressive syndrome characterized by a decline in multiple cognitive domains severe enough to impair daily functioning and reduce independence. Although memory loss is a central feature, the diagnosis requires additional deficits involving language, executive function, visuospatial skills, judgment, calculation, or abstract reasoning. These cognitive impairments reflect underlying neurodegenerative or vascular processes that gradually disrupt neuronal networks...
01:22Alzheimer's Disease: Treatment
Alzheimer's Disease (AD), a neurodegenerative disorder, is pathologically identified by amyloid plaques and neurofibrillary tangles composed of tau protein. AD pharmacotherapy aims to manage cognitive symptoms, delay disease progression, and treat behavioral symptoms. The treatment is primarily symptomatic and palliative, with no definitive disease-modifying therapy available. Cholinesterase inhibitors, including donepezil (Aricept), rivastigmine (Exelon), and galantamine (Razadyne), are...
