|
What are apolipoprotiens?
|
Apolipoprotein B (APOB or ApoB) are the primary apolipoproteins of chylomicrons and low-density lipoproteins (LDL - known commonly by the misnomer "bad cholesterol" when in reference to heart disease), which is responsible for carrying cholesterol to tissues. While it is unclear exactly what functional role APOB plays in LDL, it is the primary apolipoprotein component and is absolutely required for its formation.
Apolipoprotein A-I is the major protein component of high density lipoprotein (HDL) in plasma targets for clinically significant CAD: LDL <70 this should be replaced with an APOB goal of 80. |

|
what is the framingham risk score?
|
The Framingham Risk Score is used to estimate the 10-year cardiovascular risk of an individual. The Framingham Risk Score is based on age, total cholesterol, smoking status, HDL, and systolic BP.
The CHD risk at 10 years in percent can be calculated with the help of the Framingham Risk Score. Individuals with low risk have 10% or less CHD risk at 10 years, with intermediate risk 10-20%, and with high risk 20% or more. |

low birth weight
preterm delivery perinatal mortality postpartum depression poor performance on mental and psychomotor testing in offspring |

|
what is the most common cause of dementia?
|
alzheimers - accounts for 3/4 of dementia cases
|
|
what is the genetic RF for late alzheimers?
|
This gene, called APOE, produces a protein called apolipoprotein E. APOE comes in several forms, or alleles—ε2, ε3, and ε4:
•The APOE ε2 allele is relatively rare and may provide some protection against the disease. If AD does occur in a person with this allele, it develops later in life than in those with an APOE ε4 allele. •APOE ε3 is the most common allele. Researchers think it plays a neutral role in AD. •APOE ε4 occurs in about 40 percent of all people who develop late-onset AD and is present in about 25 to 30 percent of the population. People with AD are more likely to have an APOE ε4 allele than people who do not have AD. However, at least one-third of people with AD do not have an APOE ε4 allele. |
|
what is the main toxic substance implicated in alzheimers
|
B-amyloid has been implicated ast the toxic substance that is thought to destroy neurons by generating free radicals.
some studies have shown large amounts of antioxidants reduced the risk of AD. |
|
what is the other toxic substance implicated in alzheimers
|
homocystine can be neurotoxic and excess amounts are associ with vascular dementia and rapidly progressing AD.
Low levels of vit B6 and B12 is assoc with cognitive impairment and increased risk of AD. |
