Vascular Cognitive Impairment
Conditions
Brief summary
Vascular cognitive impairment (VCI) is a broad dimensional term, ranging from mild cognitive impairment without incapacity on activity of daily living to vascular dementia (VaD), referred to as significant cognitive impairment and decline in function status. In this three-year project, we aim to evaluate the effects of biochemical data, early clinical variables, neuroimaging results, and intervention of acupuncture treatment on vascular event related cognitive impairment in crossectional analysis and longitudinal follow-up.
Detailed description
Stroke is a common cerebrovascular disease of the central nervous system leading to serious medical complication. It results in a high mortality rate and increased disability rate. Stroke survivors may have long-lasting consequences, including motor dysfunction, sensibility dysfunction, and cognitive impairment\]. Cognition is a key component of rehabilitation and recovery; therefore it is associated with poor engagement in rehabilitee and outcomes including increased mortality. As vascular dementia (VaD) is considered the second-most-common type of dementing illness, accounting for a significant proportion of total dementia case, vascular cognitive impairment (VCI) is a broader dimensional term, ranging from mild cognitive impairment without incapacity on activity of daily living to VaD, referred to as significant cognitive impairment and decline in function status. Acupuncture is an ancient Chinese medical technique in which fine, stainless steel needles are inserted into certain anatomical locations of the body surface to elicit neurohormonal responses of the body system via nerve stimulation. Acupuncture are reported to be probably effective in improving cognitive function in vascular dementia animal models via multiple mechanisms such as anti-apoptosis, antioxidative stress reaction, and metabolism enhancing of glucose and oxygen. Motor features may not parallel to the cognitive changes, it will serve as the disease progression marker. Unified Parkinson's Disease Rating Scale (UPDRS)-part III scores and NIH Stroke Scale (NIHSS) will be used. 1. At Kaohsiung Chang Gung Memorial Hospital, all the patients (n=80) will be included and receive a Standardized Acupuncture intervention; 40 will be treated with regular medication; 40 will be treated with acupuncture and regular medication. 2. For acupressure program, all participants are treated in supine position, and a certified TCM physician applied firm pressure (3 to 5 kg of pressure) with fingertips in a circular motion at a speed of 2 circles per second for a duration of one minute per acupoint. The complete process lasts for 8 minutes. Cognitive function, Motor function, Mood and Sleep will be evaluated at baseline and follow-up period of time at 3 month, 6 month, and 12 month.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Change from baseline sleep quality at 3 months, 6 months, 12 months | 3 months, 6 months, 12 months | Analogous variables were extracted from actigraphy. The sleep variables collected were sleep start time, sleep end time, sleep duration, sleep efficiency, and wake after sleep onset time, and the activity variables collected were heart rate activity score,activity amount, and activity intensity |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Change from baseline motor function (UPDRS) at 3 months, 6 months, 12 months | 3 months, 6 months, 12 months | Unified Parkinson's Disease Rating Scale (UPDRS)-part III scores for parkinsonian features. |
| Change from baseline motor function (NIHSS) at 3 months, 6 months, 12 months | 3 months, 6 months, 12 months | NIH Stroke Scale (NIHSS) score 0-24. |
| Change from baseline continuous motor function at 3 months, 6 months, 12 months | 3 months, 6 months, 12 months | Physical activity was measured using accelerometers. |
| Change from baseline memory performances at 3 months, 6 months, 12 months | 3 months, 6 months, 12 months | Verbal memory were evaluated by using Chinese Version Verbal Learning Test (CVVLT).Visual-spatial abilities. |
| Change from baseline executive performances at 3 months, 6 months, 12 months | 3 months, 6 months, 12 months | Attention and executive function was evaluated by Trail Making Test B. |
| Change from baseline neuro-behavioral performances at 3 months, 6 months, 12 months | 3 months, 6 months, 12 months | Cognitive Abilities Screening Instrument (CASI). In addition to general cognitive performance, CASI was used to evaluate specific domains, including short-term memory, attention and concentration, abstraction, visual construction, language, and list-generating fluency. |
| Change from baseline executive performances (calculation) at 3 months, 6 months, 12 months | 3 months, 6 months, 12 months | As the calculation ability depends on executive function, calculation ability was evaluated to reflect part of executive function. |
| Change from baseline abstract thinking at 3 months, 6 months, 12 months | 3 months, 6 months, 12 months | Abstract reasoning was evaluated by using similarities (conceptualization) in frontal assessment battery-Similarities. |
| Change from baseline language performances at 3 months, 6 months, 12 months | 3 months, 6 months, 12 months | Boston Naming Test were used to evaluate language ability in naming. |
| Change from baseline fluency performances at 3 months, 6 months, 12 months | 3 months, 6 months, 12 months | Semantic category fluency. |
| Change from baseline neuropsychiatric symptoms at 3 months, 6 months, 12 months | 3 months, 6 months, 12 months | The neuropsychiatric symptoms of the participants were measured using the Neuropsychiatric Inventory. |
| Change from baseline executive performances (Stroop interference test) at 3 months, 6 months, 12 months | 3 months, 6 months, 12 months | Attention and executive function was evaluated by Stroop interference test. |
