Fibromyalgia: A Review of the Pathophysiological Mechanisms and Multidisciplinary Treatment Strategies

Fibromyalgia is a syndrome characterized by chronic widespread musculoskeletal pain, which may or may not be associated with muscle or joint stiffness, accompanied by other symptoms such as fatigue, sleep disturbances, anxiety, and depression. It is a highly prevalent condition globally, being considered the third most common musculoskeletal disorder, following lower back pain and osteoarthritis. It is more prevalent in women than in men, and although it can occur at any age, it is more common between the ages of thirty and thirty-five. Although the pathophysiology and etiopathogenesis remain largely unknown, three underlying processes in fibromyalgia have been investigated. These include central sensitization, associated with an increase in the release of both excitatory and inhibitory neurotransmitters; peripheral sensitization, involving alterations in peripheral nociceptor signaling; and inflammatory and immune mechanisms that develop concurrently with the aforementioned processes. Furthermore, it has been determined that genetic, endocrine, psychological, and sleep disorders may influence the development of this pathology. The accurate diagnosis of fibromyalgia remains challenging as it lacks specific diagnostic biomarkers, which are still under investigation. Nonetheless, diagnostic approaches to the condition have evolved based on the use of scales and questionnaires for pain identification. The complexity associated with this pathology makes it difficult to establish a single effective treatment. Therefore, treatment is multidisciplinary, involving both pharmacological and non-pharmacological interventions aimed at alleviating symptoms. The non-pharmacological treatments outlined in this review are primarily related to physiotherapy interventions. The effectiveness of physical exercise, both on land and in water, as well as the application of electrotherapy combined with transcranial therapy and manual therapy has been highlighted. All of these interventions aim to improve the quality of life of patients highly affected by fibromyalgia.

Brain stimulation found to improve vision recovery after stroke

Scientists at EPFL have developed an innovative, non-invasive brain stimulation therapy to significantly improve visual function in stroke patients who have suffered vision loss following a stroke. The approach could offer a more efficient and faster way to regain visual function in such cases.

Each year, thousands of are left with hemianopia, a condition that causes loss of half of their visual field (the “vertical midline”). Hemianopia severely affects such as reading, driving, or just walking through a crowded space.

There are currently no treatments that can restore lost visual function in hemianopia satisfactorily. Most available options focus on teaching patients how to adapt to loss of vision rather than recovering it. To achieve some degree of recovery, months of intensive neurorehabilitative training are required for only moderate restoration at best.

MIT Neuroscientist Proposes Brain Waves are the Hidden Engine Behind Thought and Consciousness

When it comes to understanding the mystery of human consciousness, scientists have long sought the hidden mechanism that transforms mere neural firing into the rich experience of thought.

Now, a leading MIT neuroscientist believes he’s found a clue that suggests the brain’s electrical waves don’t just reflect our thoughts, but actually create them.

At the Society for Neuroscience’s annual meeting on November 15, Dr. Earl K. Miller, a professor at MIT’s Picower Institute for Learning and Memory, will unveil a provocative proposal: that cognition and consciousness emerge from the fast, flexible organization of the brain’s cortex—powered by analog computations performed by traveling brain waves.

In other words, the rhythm of the brain may be more than background noise—it may be the very pulse of thought itself.

“The brain uses these oscillatory waves to organize itself,” Dr. Miller said in a press statement. “Cognition is large-scale neural self-organization. The brain has got to organize itself to perform complex behaviors. Brain waves are the patterns of excitation and inhibition that organize the brain, and this leads to consciousness because consciousness is this organized knitting together of the cortex.”

Dr. Miller’s theory revives the concept of analog computation. Unlike digital computers, which rely on discrete binary bits, analog systems process continuous information—waves interacting to produce a vast range of possible values.

Dr. Miller argues that the brain’s natural oscillations—electrical waves generated by millions of neurons—function as analog computers, sculpting information in a fast, flexible, and energy-efficient way.

Interplay Between Aging and Glial Cell Dysfunction: Implications for CNS Health

Aging is accompanied by complex cellular and molecular changes that compromise CNS function. Among these, glial cells (astrocytes, microglia, and oligodendrocytes) play a central role in maintaining neural homeostasis, modulating synaptic activity, and supporting metabolic demands. Emerging evidence indicates that aging disrupts glial cell physiology through processes including mitochondrial dysfunction, impaired proteostasis, chronic low-grade inflammation, and altered intercellular signaling. These alterations contribute to synaptic decline, myelin degeneration, and persistent, low-grade inflammation of the CNS. This review synthesizes current knowledge on the bidirectional relationship between aging and glial cell dysfunction, highlighting how age-related systemic and CNS-specific factors exacerbate glial impairments and, in turn, accelerate neural deterioration.

Memory bumps across the lifespan in personally meaningful music

You know that feeling when a song from your teenage years comes on, and suddenly you’re right back in your old bedroom, feeling everything as vividly as you did decades ago? Scientists call this the “reminiscence bump”—our strange tendency to form the most powerful, lasting emotional bonds with music we hear between ages 15 and 25. But until now, no one knew if this was just a Western phenomenon or if it looked the same for everyone, everywhere.

The study also revealed we’re not limited to just one “memory bump.” Three distinct patterns emerge: we connect with music our parents loved (cross-generational), music from our own coming-of-age years (the classic reminiscence bump), and music from recent years (the recency effect). Age and gender act like equalizers, turning up some bumps while fading others.

From the “reminiscence bump” to cross-generational musical connections, we’ll unpack the psychology and neuroscience behind your most meaningful playlists.

Some songs stay with us for a lifetime. Even decades later, a few familiar notes can unlock vivid memories. Yet the life periods from which these songs originate and their prominence across age and gender remain underexplored. This study examines lifespan patterns in music-related memory, focusing on age trends, gender differences, and the global presence of the “reminiscence bump”, a peak in emotional connection to music from adolescence and early adulthood. While this phenomenon is well-documented in Western samples, its global manifestation, gendered dimensions and variation across life stages remains unexplored. Using responses collected from 1891 participants across diverse geographical backgrounds, we analysed the release years of personally meaningful songs.
