Introduction: Pure progressive amnesia is a rare and unusual syndrome involving long preservation of autonomy and absence of progression in other cognitive domains.
Case Report: We report a case which remained quiescent for 16 years characterized by severe isolated episodic amnesia and preservation of spatial, semantic and implicit memory and autonomy. MRI revealed bilateral focal atrophy of the hippocampus.
Conclusion: This specific pattern of impairment differs from other types of amnesic syndromes. It is important to identify this kind of amnesia because of its specific course. Studying the topography of the brain lesions may contribute to a better understanding of the neural systems involved in declarative memory.

Background: Neuroinflammation plays an important role in progression of Alzheimer's disease (AD). Interlukin-6 (IL-6) is well identified marker in initiating and regulating inflammation, and formation of senile plaques in brain. Therefore, simultaneous inhibition of both IL-6 and acetylcholinesterase (AChE) may be an effective strategy for AD.

Contemporary research evidence has corroborated a gradual loss of central cholinergic neurons in Alzheimer's Disease (AD). This progressive deterioration leads to cognitive dysfunction and impaired motor activity, culminating in the brain cell's death in the disease. The approved drugs for AD treatment can only offer relief from symptoms without addressing the underlying pathological hallmarks of the disease.

Background: The term rapidly progressive dementia (RPD) describes a disorder with rapid progression which leads to a major cognitive decline in less than 1 or 2 years. Neurosyphilis is an infectious cause of RPD and it is classified clinically into early and late forms. The latter affect the brain and spinal cord parenchyma.

Objective: Mitotane is currently the only product approved by the Food and Drug Administration for the treatment of adrenocortical cancer. However, there is a lack of comprehensive studies on the adverse events of mitotane.
Methods: Adverse event reports for mitotane in the Food and Drug Administration Adverse Event Reporting System database since 2004 were collected and analyzed to identify mitotane as the primary suspect drug.
The involvement of DNA synthesis in the mechanisms of long-term memory reconsolidation in edible snails trained for conditioned food aversion was investigated. Administration of nucleoside analogs, such as 5-bromo-2'-deoxyuridine or 3'-azido-3'-deoxythymidine, which inhibit DNA synthesis, 1 h before or 1-3 h, but not 5 h after reminder with the conditioned stimulus led to memory impairment. One day after the inhibitor application and memory reactivation, a weakly expressed memory impairment (amnesia) was observed, which progressed over the next few days to the complete disappearance of behavioral memory expression.
