Summary
Patients with Amyotrophic Lateral Sclerosis (ALS) exhibit unique skin properties, including resistance to bedsores and delayed return phenomenon (DRP), suggesting novel insights into disease pathogenesis.
Area of Science:
- Neurology
- Dermatology
- Pathophysiology
Background:
- Patients with Amyotrophic Lateral Sclerosis (ALS) paradoxically do not develop bedsores, even in advanced stages.
- ALS patient skin exhibits a unique 'delayed return phenomenon' (DRP), characterized by reduced elasticity and slow recoil after stretching, typically observed years after symptom onset.
Purpose of the Study:
- To review recent research on skin characteristics in ALS patients.
- To explore potential mechanisms and pathogenesis underlying the observed skin changes in ALS.
Main Methods:
- Literature review of studies investigating skin properties in ALS patients.
- Analysis of clinical observations regarding skin elasticity and pressure sore development.
Main Results:
- Consistent observation of reduced skin elasticity and DRP in ALS patients.
- Absence of pressure ulcers in ALS patients, even at terminal stages, despite immobility.
Conclusions:
- The unique skin properties in ALS, including resistance to bedsores and DRP, warrant further investigation.
- Understanding these dermatological manifestations may provide novel insights into ALS pathophysiology and potential therapeutic targets.

Cross-bridge Cycle
As muscle contracts, the overlap between the thin and thick filaments increases, decreasing the length of the sarcomere—the contractile unit of the muscle—using energy in the form of ATP. At the molecular level, this is a cyclic, multistep process that involves binding and hydrolysis of ATP, and movement of actin by myosin.
Chemical Synapses
Chemical synapses are specialized sites between two neurons or between a neuron and a non-neuronal cell like a muscle, glandular or sensory cell.
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...

Skin Cancer
Skin cancer is a type of cancer that occurs when there is an abnormal growth of skin cells, usually triggered by damage to the DNA within the skin cells. It is primarily caused by exposure to ultraviolet (UV) radiation from the sun or artificial sources like tanning beds. Skin cancer is the most common type of cancer worldwide, and its incidence continues to rise.

Myasthenia Gravis ll: Pathophysiology
The disease process of myasthenia gravis begins at the neuromuscular junction, where antibodies attack key proteins needed for muscle activation. This immune reaction weakens signal transmission, leading to the characteristic muscle fatigue and weakness that define the condition.Immune-Mediated DamageIn most individuals, antibodies target acetylcholine receptors (AChRs) on the postsynaptic membrane of muscle cells. By blocking acetylcholine binding, these antibodies prevent the nerve signal...
Alterations in Muscle Tone lll
Rigidity and myotonia are distinct abnormalities of muscle tone that affect resistance and relaxation during movement. Although both involve altered muscle contraction, they arise from different neurological and muscular mechanisms.CharacteristicsRigidity is characterized by uniform resistance to passive movement across the entire range, independent of speed, affecting flexors and extensors equally. It may appear as lead-pipe rigidity (smooth, constant resistance) or cogwheel rigidity...
