Thought this could be of interest to the forum. The paper is paywalled except for the abstract:
Sleep loss dysregulates cellular metabolism and energy homeostasis.
Highly metabolically active cells, such as neurons, enter a catabolic state during periods of sleep loss, which consequently disrupts physiological functioning.
Specific to the central nervous system, sleep loss results in impaired synaptogenesis and long-term memory, effects that are also characteristic of neurodegenerative diseases.
In this review, we describe how sleep deprivation increases resting energy expenditure, leading to the development of a negative energy balance—a state with insufficient metabolic resources to support energy expenditure—in highly active cells like neurons.
This disruption of energetic homeostasis alters the balance of metabolites, including adenosine, lactate, and lipid peroxides, such that energetically costly processes, such as synapse formation, are attenuated.
During sleep loss, metabolically active cells shunt energetic resources away from those processes that are not acutely essential, like memory formation, to support cell survival.
Ultimately, these findings characterize sleep loss as a metabolic disorder.
