Déjà Vu: Exploring the Psychology Behind the Phenomenon

 / 

Deja vu, the uncanny feeling of a new situation appearing eerily familiar, has long intrigued scientists and psychologists. Let’s learn more about what it is.

Dr. Sanam Hafeez, a licensed clinical psychologist and neuropsychologist, sheds light on this deja vu meaning.

What Is Déjà Vu? Unraveling The Familiar Yet New Experience

Déjà vu, a French term meaning “already seen,” refers to the sensation of reliving a past experience during a new and unfamiliar situation. It’s a curious and powerful wave of familiarity in the present moment, as described by Dr. Hafeez.

The exact cause of déjà vu remains mysterious, with various theories proposed. Some experts believe it may involve delays or errors in memory retrieval, while others suggest the brain processes information through multiple pathways simultaneously.

Another theory posits that memories are stored in a complex, interconnected manner in the brain. Regardless of the mechanism, déjà vu is a common, transient experience affecting people of all ages and is not considered a pathological condition.

Approximately 60% to 70% of individuals in good health experience déjà vu at some point in their lives. This feeling can be triggered by familiar sights or sounds, making individuals feel intimately acquainted with new environments. Notably, déjà vu is more likely to occur in people aged 15 to 25, those with higher education, frequent travelers, and individuals who can recall their dreams.

Although déjà vu is a common experience, it is not typically considered a medical condition. However, certain medical conditions and neurological disorders may lead to déjà vu-like experiences, such as epilepsy, migraines, temporal lobe epilepsy, schizophrenia, and high levels of anxiety or stress.

In epilepsy, déjà vu can serve as a warning sign for an impending seizure, while some migraine sufferers may experience déjà vu as part of their aura. Temporal lobe epilepsy, a specific form of epilepsy, is associated with frequent and intense déjà vu episodes. In schizophrenia, déjà vu may occasionally be reported as a symptom among various other symptoms associated with the disorder.

Dr. Hafeez emphasizes that occasional déjà vu is not indicative of a medical condition. However, individuals who frequently experience distressing déjà vu, especially when accompanied by other unusual symptoms, should seek medical evaluation to rule out underlying medical or neurological issues.

New Study Reveals Link Between Depression, Anorexia, and Gut Microbiota

A recent study published in BMC Psychiatry sheds light on a potential connection between major depressive disorder (MDD), anorexia, and gut microbiota. Led by researchers at the First Hospital of Shanxi Medical University, the study suggests that individuals with both depression and anorexia exhibit distinct patterns in their gut bacteria, particularly involving the presence of a specific bacterium called Blautia.

Depression, characterized by persistent sadness and a loss of interest in daily activities, affects millions worldwide and is often accompanied by a high risk of suicide. Anorexia, marked by reduced appetite and distorted body image, commonly co-occurs with depression, complicating treatment efforts.

Beyond Chemical Imbalances: Researchers Shed Light on Social Root Causes Of Depression

In a recent letter to the editor published in Molecular Psychiatry, researchers led by Joanna Moncrieff present a compelling argument challenging the conventional understanding of depression. They assert that rather than being solely attributed to chemical imbalances in the brain, and discuss the social root causes of depression.

According to Moncrieff et al., the evidence for brain differences in depression is lacking, while there is substantial support for the influence of social and environmental factors on mental health.

They argue that the circumstances of life, such as stress and adversity, play a more significant role in shaping depressive symptoms than neuro

Study Reveals Presence of Microplastics in Human Brain: Concerns Rise Over Health Implications

In a groundbreaking revelation, researchers from the University of New Mexico have discovered microplastics infiltrating human brain tissue, as reported in a study published in the journal Environment Health Perspectives. The study sheds light on the pervasive presence of microplastics in various organs of the body, including the kidneys, liver, and brain.

Eliseo Castillo, an associate professor leading the research, underscores the widespread distribution of microplastics in the environment, emphasizing their presence in water sources, food items, and even the air we breathe.

Previous studies have estimated that individuals ingest approximately five grams of microplastics weekly, equivalent to the weight of a credit card.
