F09: Unspecified organic or symptomatic mental disorder

Unspecified organic or symptomatic mental disorders, as the name suggests, are a broad spectrum of mental health issues that result from physical or organic causes rather than psychological ones. These disorders can be traced back to various conditions including brain injuries, infections, or any systemic diseases that affect the nervous system. Common symptoms across this group may include memory problems, mood swings, changes in personality, and difficulty with cognitive functions like thinking, understanding, learning, and remembering. Depending on the underlying cause, the presentation and progression of these disorders can vary significantly. Some individuals may experience a gradual decline while others might show sudden and intense changes. It's important to remember that these disorders can affect anyone, regardless of age or background and that they are based in physical illness or injury impacting the brain, rather than being "all in the head."
