High-Level and Low-Level Awareness

350
Controlled processes in human consciousness represent high-alert mental states where individuals deliberately focus their attention on achieving specific goals. Controlled processes can be seen in situations like mastering new technology, where a person might become so absorbed that they ignore surrounding distractions. Such processes involve selective attention, requiring one to concentrate on particular elements of experience while disregarding others. These are governed by executive...

Higher Mental Functions of Brain: Learning and Memory

929
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...

Understanding Consciousness01:23

Understanding Consciousness

408
Consciousness can be defined as the state of being aware of and able to think about one's existence, sensations, and surroundings. It encompasses two major components: awareness and arousal. Awareness pertains to the recognition of environmental stimuli and internal states. At the same time, arousal refers to the physiological readiness to engage with these stimuli, which varies significantly between states like sleep and wakefulness.
Sleep, a crucial state, is characterized by reduced...

Dissociative Disorders01:27

Dissociative Disorders

168
Dissociative disorders represent complex psychological conditions characterized by disruptions in consciousness, memory, identity, or perception. These disruptions cause individuals to experience a disconnection from their thoughts, emotions, and memories. The phenomenon is not merely an occasional lapse in attention but a profound alteration in mental functioning that can severely impact daily life.

A hallmark feature of dissociative disorders is the dissociative fugue...

Organization of the Brain01:30

Organization of the Brain

937
The brain is an integral component of the nervous system and serves as the center for processing sensory inputs, making decisions, and directing bodily actions. This complex organ is organized into three primary sections: the hindbrain, midbrain, and forebrain, each responsible for a range of vital functions.
Hindbrain
The hindbrain, located at the base of the brain, plays a vital role in regulating automatic processes that sustain life. It includes the medulla oblongata, which is essential for...

Area of Science:

  • Cognitive Neuroscience
  • Psychiatry
  • Social Media Analysis

Background:

  • Brain fog is a colloquial term for cognitive difficulties.
  • Understanding its phenomenology is crucial for identifying underlying mechanisms.
  • This study explores first-person descriptions of brain fog.

Purpose of the Study:

  • To investigate the subjective experiences of brain fog.
  • To identify common themes and causal attributions associated with brain fog.
  • To explore the link between brain fog and various health conditions or behaviors.

Main Methods:

  • Scraping Reddit posts containing 'brain fog' in October 2021.
  • Analyzing post content for descriptions, subreddit themes, and causal attributions.
  • Focusing on first-person phenomenological descriptions.

Main Results:

  • 141 descriptions detailed forgetfulness, concentration issues, dissociation, cognitive slowness, and fatigue.
  • Over 50% of posts were in illness-related subreddits, notably COVID-19.
  • Long COVID was the most frequent self-attributed cause (10%).

Conclusions:

  • Brain fog encompasses heterogeneous experiences linked to illnesses, drugs, and behaviors.
  • Detailed descriptions are vital for understanding cognitive symptoms in health and disease.
  • Further research into these subjective experiences can elucidate pathophysiological mechanisms.
