Mediterraan-DASH-interventie voor neurodegeneratieve vertraging (MIND) Dieet bij patiënten met een beroerte
MIND-dieet en preventie van dementie bij patiënten met een ischemische beroerte
To test the effects of a 2- to 3-year intervention of the MIND diet versus usual post-stroke care on cognitive decline, the characteristic feature of dementia, and on brain biomarkers of Alzheimer's Disease (AD) and vascular disease in a Phase Ill randomized controlled trial of 250 patients hospitalized for acute ischemic stroke, aged 55 years or older, and without dementia who are discharged home following hospitalization.

Gedetailleerde beschrijving
The Mediterranean-DASH diet intervention for Neurodegenerative Delay (MIND in Stroke patients is designed to test the effects of a 2-3 year intervention of a hybrid of the Mediterranean and DASH diets, called MIND on 250 older patients, without dementia who are hospitalized for acute stroke who are discharged home following hospitalization. The MIND diet has the same basic components of the DASH and Mediterranean diets, such as emphasis on natural plant based foods and limited animal and high saturated fat foods, but uniquely specifies green leafy vegetable and berries as well as food component servings that reflect the nutrition dementia evidence. In this study we will test the effects of a 2- to 3-year intervention of the MIND diet (3 months of delivered meals followed by dietary and general stroke health counseling) versus usual post-stroke care (3 months delivered self-selected meals followed by general stroke health counseling) on change on cognitive outcomes over 24 to 36 months. Biological effects of the MIND diet will be assessed by measurement of brain macro and microstructural integrity in all trial participants. Other biochemical markers will be assessed in the entire group of 250 participants including: plasma Abeta42/beta40, brain derived neurotropic factor (BDNF) and plasma markers of oxidative stress and inflammation. The trial will examine potential effect mediators and modifiers by a number of cardiovascular risk factors, AD biomarkers and biological mechanisms. The proposed study has 3 recruitment sites, Rush University Medical Center, University of Chicago, and Advocate Christ Hospital all located in Chicago.

Actieve vergelijker: MIND DIET intervention
Allocation and blinding 3 year intervention of MIND Diet + counseling |
The MIND diet is a hybrid of the Mediterranean and DASH diets but with selected modifications based on the most compelling evidence in the diet dementia field. The MIND diet has the same basic components of the DASH and Mediterranean diets, such as emphasis on natural plant based foods and limited animal and high saturated fat foods, but uniquely specifies green leafy vegetables and berries as well as food component servings that reflect the nutrition dementia evidence. |
|
Placebo-vergelijker: Usual care diet intervention
3 year Intervention of usual care diet + counseling |
The Usual Care diet is comprised of both westernized (e.g. Steak, Mac n Cheese) and healthy ( veggie chili) food components |

Primaire uitkomstmaten
Uitkomstmaat |
Maatregel Beschrijving |
Tijdsspanne |
|---|---|---|
|
Change in global cognitive score
Tijdsspanne: 3-years
|
3-year change in global cognitive score. The global cognitive score is a composite score, based on the average of z scores of the 19 individual tests scores, with a mean of 0 and standard deviation of 1. Higher scores reflect high global cognitive function. |

Maatregel Beschrijving |
Tijdsspanne |
|---|---|---|
|
Change in brain MRI derived markers of macro and micro structural integrity (cubic Centimeters), total brain volume, hippocampal volume and white matter hyperintensity volume ( cubic centimeters)
Tijdsspanne: 3-years
|
130 participants total ( 65 in each treatment group) |
3-years

|
Change in 5 individual cognitive domains
Tijdsspanne: 3-years
|
Change in 5 individual domains that include executive functioning, perceptual speed, episodic memory, semantic and working memory. Each domain is made up of atleast 2 cognitive tests that are z scored and averaged for that domain. Higher scores on each domain reflects higher cognition in that domain. |
