Signs that may point to dementia include getting lost in a familiar neighborhood, using unusual words to refer to familiar objects, forgetting the name of a close family member or friend, forgetting old memories, not being able to complete tasks independently, etc. Stages
The course of dementia is often described in four stages that show a pattern of progressive cognitive and functional impairment. However, the use of numeric scales allows for more detailed descriptions. These scales include the Global Deterioration Scale for Assessment of Primary Degenerative Dementia (GDS or Reisberg Scale), the Functional Assessment Staging Test (FAST), and the Clinical Dementia Rating (CDR). Using the GDS, which more accurately identifies each stage of the disease progression, a more detailed course is described in seven stages – two of which are broken down further into five and six degrees. Stage 7(f) is the final stage. Pre-dementia
Pre-dementia states include pre-clinical and prodromal stages. The prodromal stages includes (1) mild cognitive impairment (MCI), (2) delirium-onset, and psychiatric-onset presentations. Pre-clinical
Sensory dysfunction is claimed for this stage which may precede the first clinical signs of dementia by up to ten years. Most notably the sense of smell is lost. The loss of the sense of smell is associated with depression and loss of appetite leading to poor nutrition. It is suggested that this dysfunction may come about because the olfactory epithelium is exposed to the environment. The lack of blood–brain barrier protection here means that toxic elements can enter and cause damage to the chemosensory networks.
Reticular erythematous mucinosis (REM) is a skin condition caused by fibroblasts producing abnormally large amounts of mucopolysaccharides. It is a disease that tends to affect women in the third and fourth decades of life. : 187
