Glucocorticoids and the Brain after Critical Illness.

Endocrinology 2021 03;162(3)

Michigan Neuroscience Institute, University of Michigan, Ann Arbor, MI, USA.

Treatment for critical illness typically focuses on a patient's short-term physical recovery; however, recent work has broadened our understanding of the long-term implications of illness and treatment strategies. In particular, survivors of critical illness have significantly elevated risk of developing lasting cognitive impairment and psychiatric disorders. In this review, we examine the role of endogenous and exogenous glucocorticoids in neuropsychiatric outcomes following critical illness. Read More

Neuropsychiatric Disorders Due to Limbic Encephalitis: Immunologic Aspect.

Int J Mol Sci 2020 Dec 31;22(1). Epub 2020 Dec 31.

Department of Pediatrics, National Taiwan University Hospital, Taipei 100226, Taiwan.

Limbic encephalitis (LE) is a rare cause of encephalitis presenting as an acute and subacute onset of neuropsychiatric manifestations, particularly with memory deficits and confusion as core features, along with seizure occurrence, movement disorders, or autonomic dysfunctions. LE is caused by neuronal antibodies targeting the cellular surface, synaptic, and intracellular antigens, which alter the synaptic transmission, especially in the limbic area. Immunologic mechanisms involve antibodies, complements, or T-cell-mediated immune responses in different degree according to different autoantibodies. Read More

Restructuring Blank Spaces: The Role of Cognitive-Behavioral Interventions for Two Patients With Post-traumatic Amnesia After Severe Traumatic Brain Injury.

Mil Med 2019 01;184(1-2):e266-e271

Department of Psychiatry, University of Illinois College of Medicine, 912 S. Wood Street, MC 913, Chicago, IL.

Differentiation of symptoms associated with post-traumatic amnesia (PTA) versus post-traumatic stress symptoms (PTSS) following trauma presents many treatment challenges among veterans and active duty service members receiving rehabilitation after traumatic brain injury (TBI). The acute phase of rehabilitation poses difficulties for amnestic individuals that may elicit classic PTA symptoms as well as premorbid PTSS, thereby activating maladaptive cognitions and an increase in agitation and arousal. Historically, explicit learning and memory strategies were considered non-efficacious with amnestic individuals until PTA resolves; therefore, rehabilitation therapies have utilized implicit learning in the initial phases of recovery.

Prodromal stage of disease (dementia) with Lewy bodies, how to diagnose in practice?

Geriatr Psychol Neuropsychiatr Vieil 2017 Jun;15(2):196-204

Centre de gériatrie et CM2R Île de France Sud, Hôpital Pitié-Salpêtrière, AP-HP, Paris, France, Université Pierre et Marie Curie et DHU FAST, UMR 8256 (CNRS), Paris, France.

Disease with Lewy bodies or dementia with Lewy bodies (DLB), particularly at the prodromal stage, is a complex disease to diagnose because of different clinical beginnings and variable paths in terms of clinical expression. Thus DLB can be entcountered in different input modes: mild cognitive impairment, depression, acute behavioral disorders, confusion and delirium, or sleep disorders. In the aim to better diagnose the disease, should be sought obviously to search for the key symptoms: fluctuations, hallucinations, extra-pyramidal syndrome, and REM sleep behavior disorder.
