Brain Fog

Brain fog is a non-medical term used to describe a collection of cognitive symptoms that affect thinking, focus, memory, and mental clarity. It is not a formal medical diagnosis, but it is a commonly reported experience associated with a wide range of physical, psychological, and lifestyle factors. Brain fog may be temporary or persistent depending on its underlying cause.¹²

Brain fog is often described as feeling mentally “cloudy,” slow, or unfocused, and it can significantly impact daily functioning, productivity, and quality of life.

Common Symptoms and Signs:

Brain fog refers to impaired cognitive function that may include difficulty concentrating, reduced mental clarity, and slowed thinking. It is often a symptom rather than a standalone condition and may be linked to issues such as sleep disruption, stress, hormonal changes, inflammation, or underlying medical conditions.³

Common contributing systems include:

Nervous system regulation
Sleep-wake cycle disruption
Immune system activation
Hormonal imbalance
Nutritional status

Brain fog may occur in both healthy individuals under stress and those with chronic medical conditions.
