Episodic Memory. The temporal lobe, which contains the hippocampus, in addition to the prefrontal cortex are of import to episodic memory, which enables us to acquire novel information in addition to shout upwards recent events. The hippocampus is i of the kickoff encephalon structures damaged inwards Alzheimer's illness in addition to accounts for i hallmark of early on Alzheimer's: difficulty remembering recent events, alongside picayune problem remembering events from long ago.

This organisation equally good involves the temporal lobes and, researchers suspect, multiple areas inside the cortex. People alongside Alzheimer's illness may endure unable to parent a mutual object or to listing objects inwards a category, such equally farm animals or types of birds.
Procedural Memory. The cerebellum is i of the structures involved inwards procedural memory. Procedural retentiveness is what enables people to acquire skills that volition in addition to hence move automatic (unconscious), such equally typing or skiing. This retentiveness organisation typically is non damaged inwards Alzheimer's illness or is i of the terminal cognitive domains to deteriorate.
Working Memory. Working retentiveness involves primarily the prefrontal cortex. This retentiveness organisation governs attention, concentration, in addition to the short-term retention of needed information, such equally a street address or telephone number. Problems alongside working retentiveness tin impair a person's might to pay attending or to arrive at multi-step tasks.
