Specific mutations lead to early-onset Alzheimer disease, whereas other mutations are associated with late-onset. The patient does not have relatives with the condition. The size of the brain increases in Alzheimer disease. True or false - correct answers FALSE Cell death in Alzheimer disease leads to a reduced size of the brain, with wider sulci and enlarged ventricles. Is brain cell loss in Alzheimer disease confined to a specific area of the brain? - correct answers No. Brain cell loss in Alzheimer disease is widespread throughout the brain, typically beginning in the hippocampus and frontal lobes but progressing widely. WGU D115 Unit 3 Exam Questions and Answers (Latest Update ) Verified Answers Alzheimer disease is characterized by a marked decrease in acetylcholine.

WGU D115 Unit 3 Exam Questions and Answers (Latest Update ) Verified Answers X-linked gene alterations Maternal anorexia Toxic-induced chromosomal defects Prenatal physical abuse of the mother Autosomal gene alterations - correct answers Autosomal recessive genetic alterations or defects in any 1 of 16 chromosomes can cause primary microcephaly (present at birth). Microcephaly may be caused by X-linked genetic disorders with the altered gene on the X chromosome. Environmental causes that include toxin exposure, radiation, intrauterine infection, or chemical exposure may be the initiating factor in secondary microcephaly. Maternal anorexia has been shown to have an almost twofold risk of microcephaly. Other causes can include infection, trauma, metabolic disorders, and the presence of other genetic syndromes. What test do you do for a child with frequent headaches - correct answers Headaches in children are unusual and require investigation. Headaches and nausea in the morning may indicate increased intracranial pressure. The pressure increases while the head is in a dependent or flat position due to a reduction in venous drainage.
