Abstract:
We herein report the case of a patient who showed pure anomia and amnesia caused by hemorrhage in the left thalamus, involving the anterior, ventral anterior, and mediodorsal nuclei. It was revealed that the anomia was characterized by impaired retrieval of object names, which was more pronounced in artificial objects, and abundant perseveration, whereas the amnesia was mild and limited to daily routine events, which was made clear from the results of an episodic memory scale. Detailed lesion localization and literature review revealed that a combination of pure anomia and amnesia can occur in a lesion involving the anterior, ventral anterior, or mediodorsal nucleus of the thalamus. The relative specificity to artificial objects can be explained by the locally damaged fiber connection to the putative category-specific lexical area in the temporal lobe.

Amnesia
The severity and duration of memory loss vary depending on the type and underlying cause. Amnesia is classified into two main types: retrograde and anterograde.
Retrograde amnesia is marked by the loss of memories formed before the onset of the condition. Patients may recall distant past events but often forget those occurring shortly before the incident.
