Are Mild Diffuse Brain Volume Loss And Mild Chronic Small Vessel Ischemic Changes Serious Concerns?

I am 66 years old, and have bipolar 1 disorder. I just got the results of an MRI: HISTORY: Dementia; Cognitive impairment without underlying source identifies.. Symptoms for 5 years COMPARISON: None. TECHNIQUE: 16 mL MultiHance was injected IV. Precontrast and postcontrast multiplanar MR images were obtained of the brain. FINDINGS: Brain and dura: There are a few scattered nonspecific punctate foci of increased white matter signal. Brain volume loss is present. No bleed, edema, or mass/mass effect. Ventricles and sulci: Normal. Vessels: Vascular flow voids are preserved. Calvarium: Marrow signal is normal. Craniocervical junction is intact. Orbits, sinuses, and facial soft tissues: Normal. IMPRESSION: Mild diffuse brain volume loss and mild chronic small vessel ischemic changes. I also had 7-1/2 hours of testing with a neuropsychologist. I m waiting for an appointment with a neurologist. I m starting to be scared.
