Absence or deficiency of dopamine, serotonin, oxytocin, and endorphins

By SWA

The absence or deficiency of dopamine, serotonin, oxytocin, and endorphins can lead to various mental and physical health issues. Here’s a detailed look at the effects of each deficiency:

Dopamine

Dopamine is crucial for reward, motivation, and motor functions. A deficiency can lead to:

  • Depression: Feelings of sadness, hopelessness, and lack of motivation.
  • Anhedonia: Inability to feel pleasure from activities that were once enjoyable.
  • Fatigue and Sleep Issues: Persistent tiredness and sleep disturbances.
  • Cognitive Impairment: Problems with memory, attention, and decision-making.
  • Motor Symptoms: In severe cases, such as Parkinson’s disease, it can cause tremors, muscle stiffness, and balance issues​ (Verywell Mind)​​ (Cleveland Clinic)​​ (Verywell Mind)​.

Serotonin

Serotonin regulates mood, sleep, and appetite. A deficiency can result in:

  • Depression and Anxiety: Increased risk of mood disorders.
  • Sleep Problems: Insomnia or disrupted sleep patterns.
  • Irritability: Increased agitation and mood swings.
  • Digestive Issues: Problems like irritable bowel syndrome (IBS).
  • Cognitive Impairments: Issues with memory and learning​ (Verywell Mind)​​ (Cleveland Clinic)​.

Oxytocin

Oxytocin is known as the "love hormone" and is important for social bonding. A deficiency can cause:

  • Social Anxiety: Difficulty forming and maintaining social relationships.
  • Emotional Distance: Trouble feeling empathy and emotional connection.
  • Increased Stress: Difficulty managing stress.
  • Trust Issues: Problems with trust and bonding.
  • Postpartum Depression: Contributing factor to postpartum depression in new mothers​ (Verywell Mind)​​ (Verywell Mind)​.

Endorphins

Endorphins are natural painkillers that also promote pleasure. A deficiency can lead to:

  • Chronic Pain: Increased sensitivity to pain.
  • Depression: Feelings of sadness and an inability to enjoy life.
  • Stress: Higher levels of stress and poor stress management.
  • Addiction: Increased likelihood of substance abuse.
  • Mood Swings: Frequent and intense mood changes​ (Verywell Mind)​​ (Cleveland Clinic)​.

Neurotransmitter Sources

  • Dopamine: Substantia nigra and ventral tegmental area (VTA) of the midbrain.
  • Serotonin: Raphe nuclei in the brainstem.
  • Oxytocin: Hypothalamus (released via the posterior pituitary).
  • Endorphins: Hypothalamus and pituitary gland.

These neurotransmitters and hormones play vital roles in maintaining mental and physical health. Deficiencies can lead to a range of symptoms that significantly impact daily functioning and quality of life. Treatment typically involves medication, therapy, lifestyle changes, and sometimes dietary supplements to address these imbalances.

Toxic Skin Condition Post-mRNA COVID-19 Vaccination

Identifying Severe Skin Conditions Post-Vaccination Following administration of the BioNTech mRNA vaccine, a small subset of individuals may develop severe and complex reactions. These reactions are often misdiagnosed or misunderstood due to their rarity and diverse presentation. This essay examines a case characterized by severe skin conditions, systemic symptoms, and complications such as hypercalcemia and crystal formation. It highlights the need for accurate diagnosis, holistic management, and increased awareness of these rare but significant vaccine-related adverse events. Initial Symptoms and Misdiagnoses Severe symptoms began shortly after the first dose of the BioNTech vaccine, initially presenting as petechiae, diagnosed by a rheumatologist. However, following the second dose, symptoms rapidly escalated, resulting in intense burning pain and thinning of the skin. The skin on the legs and thighs became paper-thin and could tear with the slightest touch, with the affected area e...

Dysferlin Protein: Key Roles, Genetic Locations

By SWA

The purpose of this article is to share and discuss the details of a new discovery, which is highlighted within: CRISPR-Cas9: A Breakthrough Tool to Repair the DYSF Gene The dysferlin protein plays an essential role in maintaining the integrity of muscle cell membranes, particularly in tissues that endure significant mechanical stress, such as skeletal and cardiac muscles . Encoded by the DYSF gene , dysferlin is indispensable for repairing damaged cell membranes after injury caused by muscle contraction or external forces. This article explores the main locations where dysferlin is produced, its role in muscle repair, and supportive nutritional and therapeutic strategies for individuals with dysferlin deficiency, such as those affected by dysferlinopathies (e.g., Limb-Girdle Muscular Dystrophy Type 2B or Miyoshi Myopathy). Currently, there is no definitive answer as to why the severity of dysferlin protein expression or depletion varies. Do pathogens play a role in the methylation o...

Is ME CFS connected to Spinal Muscular Atrophy (SMA) or Post Polio?

By SWA

Today, I understand why Spinal Muscular Atrophy (SMA) received little attention, particularly in the mid-50s. This complex and debilitating genetic illness was poorly understood, and patients' symptoms were often minimized or even dismissed. For more information, please visit the Spinal Muscular Atrophy (SMA) page on MalaCards . Even now, many neurologists lack detailed knowledge of SMA, and comprehensive examinations mentioned in research are rarely pursued. In 2008, while investigating permanent adrenal insufficiency, an MRI ordered by my endocrinologist unexpectedly revealed Chiari Malformation II. However, surgery in 2009 brought no improvement. In 2010, a DNA test showed a genetic marker in the ACTN3 gene: https://www.malacards.org/search/results?q=ACTN3%20gene%20and%20Spinal%20Muscular%20Atrophy%20(SMA) A 2015 MRI revealed ankylosing spondylitis, multiple Tarlov cysts, stenosis at L4 and L5, spinal canal narrowing, and widespread degenerative changes. Surgery on L4 and L5 ...
