This is the correct answer. Declarative memory is a category of long-term memory that includes facts, knowledge, and events that can be consciously recalled and verbally expressed. It can be further categorised into semantic memory, episodic memory, autobiographical memory and visual memory. It is distributed widely across the neocortex and is impaired in the early stages of Alzheimer's dementia.

Implicit memory, also known as non-declarative memory, consists of memories that are outside of conscious awareness. This includes memory of skills or actions that can be performed without thinking. Implicit memory is typically preserved in early stages of Alzheimer's dementia.

Working memory refers to the short-term storage and manipulation of information for brief periods, typically seconds to minutes. Advanced Alzheimer's dementia can affect short-term memory to some extent, but it is the long-term memory that is more profoundly impacted and is more noticeably impaired during early stages.

Long-term memory includes both declarative memory and procedural memory. Although declarative memory is impaired in early-stage Alzheimer's dementia, procedural memory, which is responsible for the learning and execution of motor skills and habits, tends to be relatively preserved in the early stages. Procedural memory is closely associated with the basal ganglia and the cerebellum, whereas declarative long-term memory is more widely distributed across the neocortex.

Sensory memory is a very brief stage of memory that involves the temporary storage of sensory information for very short periods, typically fractions of a second to a few seconds. Sensory memory is not typically impaired in early-stage Alzheimer's dementia.
