The Claim
In individuals with Alzheimer’s disease, the presence of concomitant Lewy body pathology, detected via cerebrospinal fluid seed amplification assays, is associated with a 15% faster rate of global cognitive decline over time compared to individuals with Alzheimer’s pathology alone, as measured by the Preclinical Alzheimer Cognitive Composite and Mini-Mental State Examination.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
People with Alzheimer’s who also have another brain condition called Lewy bodies tend to forget things and lose mental skills 15% faster than those with just Alzheimer’s. This was measured using standard memory and thinking tests.
See the scientific wording
In individuals with Alzheimer’s disease, the presence of concomitant Lewy body pathology, detected via cerebrospinal fluid seed amplification assays, is associated with a 15% faster rate of accelerated global cognitive decline over time compared to those with Alzheimer’s pathology alone, as measured by the Preclinical Alzheimer Cognitive Composite and Mini-Mental State Examination, suggesting that Lewy body co-pathology significantly worsens prognosis in symptomatic Alzheimer’s disease.
What the research says
1 studyStudy: Lewy body pathology exacerbates brain hypometabolism and cognitive decline in Alzheimer’s disease
People with Alzheimer’s who also have Lewy bodies in their brain (detected by a spinal fluid test) lose their memory and thinking skills faster than those with Alzheimer’s alone. This means having both conditions makes the disease worse.
