- Vascular dementia
Vascular dementia, also known as multi-infarct dementia (MID) and vascular cognitive impairment (VCI), is dementia caused by problems in the supply of blood to the brain, typically a series of minor strokes, leading to worsening cognitive decline that occurs step by step. The term refers to a syndrome consisting of a complex interaction of cerebrovascular disease and risk factors that lead to changes in the brain structures due to strokes and lesions, and resulting changes in cognition. The temporal relationship between a stroke and cognitive deficits is needed to make the diagnosis.
- Vision rehabilitation
Vision rehabilitation (often called vision rehab) is a term for a medical rehabilitation in order to improve vision or low vision. In other words, it is the process of restoring functional ability and improving quality of life and independence in an individual who has lost visual function through illness or injury. Most visual rehabilitation services are focused on low vision, which is a visual impairment that cannot be corrected by regular eyeglasses, contact lenses, medication, or surgery. Low vision interferes with the ability to perform everyday activities. Visual impairment is caused by various factors including brain damage, vision loss, and others. There are various types of vision rehabilitation techniques available, most which center on neurological and physical approaches.

- Visual impairment
Visual impairment (or vision impairment) is vision loss (of a person) to such a degree as to qualify as an additional support need through a significant limitation of visual capability resulting from either disease, trauma, or congenital or degenerative conditions that cannot be corrected by conventional means, such as refractive correction or medication.
