A psychodiagnostic investigation included 71 patients with Hodgkin's disease and 61--with non-Hodgkin's lymphoma at different stages. It was shown that anosognosia, i.e. involuntary protective rejection of the disease, may play a dual role in formation of attitude. It may range from alleviation of psychological trauma to mis-assessment of the situation. Proper understanding of psychological processes involved in such disease may help when dealing with cancer patients.

The perspective article explores systemic issues in psychiatric care, particularly the barriers to timely treatment and the ethical dilemmas involved in involuntary interventions. It further examines the impact of anosognosia-lack of disease insight-on treatment, noting the difficulties in managing care for those unaware of their illness, and scrutinizes training materials from international organizations that might mislabel necessary psychiatric practices as human rights violations, thereby complicating the care landscape. The discussion extends to the legal and societal implications of psychiatric interventions, using Massachusetts' Rogers Guardianship as a case study to highlight the consequences of legalistic approaches to mental health treatment.

Alzheimer's disease (AD) encompasses a long continuum from a preclinical phase, characterized by neuropathological alterations albeit normal cognition, to a symptomatic phase, marked by its clinical manifestations. Yet, the neural mechanisms responsible for cognitive decline in AD patients remain poorly understood. Here, we posit that anosognosia, emerging from an error-monitoring failure due to early amyloid-β deposits in the posterior cingulate cortex, plays a causal role in the clinical progression of AD by preventing patients from being aware of their deficits and implementing strategies to cope with their difficulties, thus fostering a vicious circle of cognitive decline.

Long-lasting pure topographical disorientation due to heading disorientation following left retrosplenial infarction: A report of two cases.

Brain Cogn

November 2024

Department of Behavioral Neurology and Cognitive Neuroscience, Graduate School of Medicine, Tohoku University, Japan. Electronic address:

Topographical disorientation is linked to lesions in the right hemisphere and typically resolves within a few months post-stroke. Persistent topographical disorientation is uncommon and frequently accompanied by impairments in visual memory, complicating the analysis of the underlying mechanisms. Herein, we report two cases of sustained pure topographical disorientation following cerebral hemorrhages in the left retrosplenial region.
