Dementia l: Introduction

Dementia l: Introduction

Dementia is an acquired, progressive syndrome characterized by a decline in multiple cognitive domains severe enough to impair daily functioning and reduce independence. Although memory loss is a central feature, the diagnosis requires additional deficits involving language, executive function, visuospatial skills, judgment, calculation, or abstract reasoning. These cognitive impairments reflect underlying neurodegenerative or vascular processes that gradually disrupt neuronal networks...

Amnesia

Amnesia

Amnesia is a condition marked by long-term memory loss, which impairs the ability to recall past events or create new memories.
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.
Anterograde...

Hepatic Encephalopathy

Hepatic Encephalopathy

DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic shunting—including...

Alzheimer Disease l: Introduction

Alzheimer Disease l: Introduction

Alzheimer disease is a chronic, progressive, and irreversible neurodegenerative disorder and the most common cause of dementia in older adults. It leads to gradual neuronal loss, causing cognitive decline, behavioral changes, and loss of functional independence.Risk Factors and EtiologyThe disease is multifactorial. Age is the strongest risk factor, with prevalence doubling every 5 years after age 65. Genetic factors include mutations in genes such as APP, PSEN1, and PSEN2, which are associated...

Role of Cerebellum and Prefrontal Cortex in Memory

Role of Cerebellum and Prefrontal Cortex in Memory

The cerebellum, while traditionally associated with motor control, also plays a crucial role in memory, particularly in procedural memory, which involves learning motor tasks that become automatic through repetition. For example, studies have shown that when the cerebellum is damaged, individuals or animals lose the ability to learn conditioned motor responses, such as the conditioned eye-blink response in classical conditioning experiments with rabbits. This study demonstrates the cerebellum's...

Higher Mental Functions of Brain: Learning and Memory

Higher Mental Functions of Brain: Learning and Memory

Memory is one of the most vital higher mental functions of the brain. Memory is closely related to learning because it enables us to retain information and experiences from our past to use them in our present life. It also helps us to remember facts, events, and skills, such as riding a bike or swimming. There are two types of memory — declarative memory, which involves memorizing facts or events, and procedural memory, which enables us to remember how to do something like writing or playing an...

Summary

Neuro-Behcet's disease can cause severe memory and executive dysfunction, mimicking diencephalic amnesic syndrome. Brain imaging revealed thalamic and subcortical-frontal pathway involvement in a 48-year-old patient.

Area of Science:

Neurology
Neuroimmunology
Neuropsychology

Background:

Neuro-Behcet's disease is a rare systemic vasculitis affecting the central nervous system.
Neurological manifestations can be diverse, impacting cognitive functions.

Observation:

A 48-year-old patient presented with profound memory loss and frontal/executive deficits.
Clinical presentation resembled diencephalic amnesic syndrome.

Findings:

Magnetic Resonance Imaging (MRI) and Single-Photon Emission Computed Tomography (SPECT) indicated thalamic abnormalities.
Evidence suggested dysfunction in the subcortical-frontal connections linked to the thalamus.

Implications:

Highlights the thalamus and its connections as critical in neuro-Behcet's related cognitive impairment.
Suggests specific neuroimaging techniques for diagnosing cognitive deficits in neuro-Behcet's disease.
Underscores the importance of considering neuro-Behcet's disease in patients with unexplained amnesia and executive dysfunction.
