In simple words: A type of memory loss and cognitive decline where the cause isn't clearly defined, and the symptoms are noticeable enough to affect daily activities.

A form of dementia that doesn't fit into the specific types like Alzheimer's or vascular dementia, and is characterized by a moderate decline in cognitive abilities, including memory, thinking, and reasoning, significantly impacting daily life.

Example 1: A 65-year-old patient presents with gradual memory loss, difficulty with problem-solving, and changes in personality. After ruling out other causes of dementia, the physician diagnoses unspecified dementia, moderate., A patient with a history of head trauma experiences progressive cognitive decline, including impaired judgment and language difficulties.Following neurological evaluations, F03.B is assigned due to the moderate level of impairment., A patient with a known history of cerebrovascular disease displays moderate cognitive deficits consistent with vascular dementia.However, due to the mixed etiology potentially involving other factors and an unclear primary cause, the physician uses F03.B for a more generalized representation.

Documentation should include detailed clinical findings of cognitive decline, including memory impairment, language difficulties, and executive dysfunction.Evidence of functional limitations in daily life should be noted. Diagnostic tests like neuropsychological evaluations, brain imaging scans, and laboratory tests used to rule out other conditions should be documented. The underlying physiological condition contributing to the dementia should be specified if known. The severity level (moderate) should be supported by objective clinical findings.

** Excludes1: senility NOS (R41.81)Excludes2: mild memory disturbance due to known physiological condition (F06.8) senile dementia with delirium or acute confusional state (F05)
