Retrieval and encoding of episodic memory in normal aging and patients with mild cognitive impairment.

We investigated retrieval and encoding of episodic memory in normal aging and patients with mild cognitive impairment (MCI). There was significant decline in the function of orientation, language and praxis besides memory impairment in the MCI group. Impairment of encoding and retrieval of episodic memory was observed in the MCI group. Encoding of episodic memory is vulnerable to be impaired in the MCI group.
