Fragmented or lower sleep efficiency may affect executive function as it is linked to decline in cognitive abilities of older people over a period of three to four years, a study has found.

Poor sleep quality is associated with a 40 to 50 percent increase in the odds of clinically significant decline in executive function, which was similar in magnitude to the effect of a five-year increase in age, a research says.

This study provides an important reminder that healthy sleep involves both the quantity and quality of sleep.

According to the study authors, executive function is the ability for planning or decision making, error correction or trouble shooting and abstract thinking.
