Memory loss is the partial or complete inability to recall past experiences, information, or skills. It can affect short-term memory, long-term memory, or both. Causes range from stress, poor sleep, and nutritional deficiencies to neurological conditions such as Alzheimer’s disease, stroke, or brain injury. Medications, alcohol, and hormonal changes can also play a role. While occasional forgetfulness is common with ageing, persistent or worsening memory loss may signal deeper imbalances in brain health. Identifying root causes through lifestyle review, cognitive testing, and advanced lab work is vital for creating strategies to protect, support, and improve memory function.
