Wilhelm Uhthoff: a phenomenon 1853 to 1927
1Department of Neurology and Neurorehabilitation, Rehabilitation Centre, Valens, Switzerland.
Summary
Wilhelm Uhthoff discovered that increased body temperature can cause temporary vision loss in multiple sclerosis patients. This finding advanced the understanding of transient visual disturbances in neurological conditions.
Area of Science:
- Neurology
- Ophthalmology
- Clinical Medicine
Background:
- Wilhelm Uhthoff (1853-1927) was a notable figure in 19th and 20th-century neurology and ophthalmology.
- His work significantly contributed to understanding neurological disorders and their visual manifestations.
Discussion:
- Uhthoff's primary contribution is the description of exercise-induced transient visual disturbances.
- He identified a link between elevated body temperature and temporary vision impairment in patients with multiple sclerosis (MS).
Key Insights:
- The Uhthoff phenomenon describes temporary vision worsening with heat or exertion in MS.
- This observation was crucial for understanding the pathophysiology of visual symptoms in demyelinating diseases.
Outlook:
- Uhthoff's findings remain relevant for diagnosing and managing visual symptoms in MS.
- Further research continues to explore the mechanisms behind thermolability in neurological conditions.

Generating Electromagnetic Radiations
The German physicist Heinrich Hertz (1857–1894) was the first to generate and detect certain types of electromagnetic waves in the laboratory. Starting in 1887, he performed a series of experiments that confirmed the existence of electromagnetic waves and verified that they travel at the speed of light. Hertz used an alternating-current RLC (resistor-inductor-capacitor) circuit that resonated at a known frequency and connected it to a loop of wire. High voltages induced across the gap in the...
Freudian Psychology
Sigmund Freud, an Austrian neurologist born in 1856, significantly influenced psychology through his exploration of the unconscious mind. His interest in patients suffering from hysteria and neurosis — conditions without apparent physical causes — led him to theorize the existence of an unconscious mind, a repository for feelings and urges beyond our awareness. Freud's innovative approach included techniques such as dream analysis, free association, and attention to slips of the tongue to...

Maxwell's Equation Of Electromagnetism
James Clerk Maxwell (1831–1879) was one of the major contributors to physics in the nineteenth century. Although he died young, he made major contributions to the development of the kinetic theory of gases, to the understanding of color vision, and to understanding the nature of Saturn's rings. He is probably best known for having combined existing knowledge on the laws of electricity and magnetism with his insights into a complete overarching electromagnetic theory, which is represented by...
Gestalt Psychology
Gestalt psychology, founded by Max Wertheimer, Kurt Koffka, and Wolfgang Kohler, emphasizes the importance of understanding perception as an organized whole. Developed as a counter to Wilhelm Wundt's structuralism, this approach posits that our perceptions are more than just the sum of sensory parts; they are comprehensive wholes where the relationships between parts define the perception. The principle "The whole is greater than the sum of its parts" encapsulates this view, illustrating how...
Electrolytes: van't Hoff Factor
Colligative Properties of ElectrolytesThe colligative properties of a solution depend only on the number, not on the identity, of solute species dissolved. The concentration terms in the equations for various colligative properties (freezing point depression, boiling point elevation, osmotic pressure) pertain to all solute species present in the solution. Nonelectrolytes dissolve physically without dissociation or any other accompanying process. Each molecule that dissolves yields one dissolved...
