Summary
Dehydroepiandrosterone (DHEA) and its sulphate (DHEAS) are key adrenal hormones influencing brain function. This review explores their synthesis, regulation, stress response, and therapeutic potential for central nervous system disorders.
Area of Science:
- Endocrinology and Neurobiology
- Steroid hormone synthesis and neurosteroidology
Context:
- Dehydroepiandrosterone (DHEA) and dehydroepiandrosterone sulfate (DHEAS) are the most abundant steroid hormones produced by the adrenal glands.
- Neurosteroids play crucial roles in modulating brain function.
Purpose:
- To review the synthesis pathways and regulatory mechanisms of neurosteroids, specifically DHEA and DHEAS.
- To examine the dynamics of DHEA(S) under stressful conditions.
- To analyze the role of DHEAS in various cerebral functions and its therapeutic application in CNS disorders.
Summary:
- The review details the synthesis of neurosteroids, focusing on DHEA and DHEAS, and their regulatory mechanisms.
- It analyzes the impact of stress on DHEA(S) levels and function.
- Experimental and clinical data on DHEAS's role in cognitive functions, mood, and sleep are presented.
Impact:
- Highlights the significance of DHEA(S) in maintaining central nervous system (CNS) homeostasis.
- Provides insights into the potential of DHEA(S) substitutive therapy for neurodegenerative and psychiatric conditions.
- Discusses therapeutic strategies for Alzheimer's disease, depression, and age-related memory and sleep disturbances.

01:37Hypothalamic-Pituitary Axis
The response to stress—be it physical or psychological, acute or chronic—involves activation of the Hypothalamic-Pituitary-Adrenal (HPA) axis. The HPA axis is part of the neuroendocrine system because it involves both neuronal and hormonal communication. Its function is to regulate homeostatic systems—metabolic, cardiovascular, and immune—providing the necessary means to respond to a stressor.
01:31Hormones of the Adrenal Glands
Adrenal hormones play a pivotal role in maintaining the body's electrolyte balance and orchestrating responses to stress, showcasing the intricate functions of the adrenal cortex and medulla.
The adrenal cortex, a powerhouse of hormone synthesis, generates over two dozen corticosteroid hormones. The zona glomerulosa produces mineralocorticoids, exemplified by aldosterone, influencing the electrolyte composition of body fluids. The synthesis of glucocorticoids such as cortisol and corticosterone...

01:02The Pineal Gland
The pineal gland, a diminutive endocrine structure named for its pinecone-shaped appearance, is situated atop the third ventricle within the diencephalon region of the forebrain. This gland, composed of secretory cells known as pinealocytes arranged in compact cords and clusters around dense particles of calcium salts, plays a pivotal role in hormonal regulation.
The primary secretion of the pineal gland is the hormone melatonin, derived from serotonin. The concentration of melatonin in the...

01:24Gonadal and Placental Hormones
The gonads, namely the testes in males and the ovaries in females, are pivotal in producing gonadal hormones that orchestrate the intricate processes of sexual development and reproduction.
In males, testosterone is the primary gonadal androgen. It plays a central role in the maturation of male reproductive organs — the penis and testes. Additionally, testosterone is instrumental in the development of secondary sexual characteristics — a deep voice as well as facial and pubic hair growth — and...

01:26Testosterone: Functions and Regulation
The intricate hormonal interplay essential for male reproductive health begins with the release of gonadotropin-releasing hormone (GnRH) by the hypothalamus. This hormone prompts the pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). LH targets the Leydig cells in the testes, stimulating them to produce and release testosterone. In concert with testosterone, FSH acts on the Sertoli cells within the seminiferous tubules to facilitate the release of...
01:27Major Hormones and Their Functions
Hormones, the biochemical messengers produced by endocrine glands, are pivotal in regulating bodily functions and maintaining homeostasis. Each hormone's balance is crucial; imbalances can lead to significant physiological disruptions. Major hormones include oxytocin, cortisol, epinephrine, estrogen, testosterone, thyroxine, growth hormone, insulin, and glucagon.
Oxytocin, produced in the hypothalamus and released by the pituitary gland, plays a role in social bonding, childbirth, and lactation.
