Amyotrophic lateral sclerosis with ophthalmoplegia. A clinicopathologic study
Archives of Neurology
|October 1, 1979
Summary
Ophthalmoplegia, or eye movement paralysis, is a rare symptom in amyotrophic lateral sclerosis (ALS). This case study details the specific neuropathological findings in the brainstem nuclei of an ALS patient with progressive ophthalmoplegia.
Area of Science:
- Neurology
- Neuroscience
- Ophthalmology
Background:
- Amyotrophic lateral sclerosis (ALS) is a progressive neurodegenerative disease primarily affecting motor neurons.
- Ophthalmoplegia, characterized by paralysis of eye muscles, is an uncommon manifestation of ALS.
Observation:
- This report details a unique case of ALS presenting with progressive ophthalmoplegia.
- The patient experienced a gradual decline in extraocular muscle function throughout the disease course, culminating in total paralysis.
Findings:
- Postmortem examination revealed significant neuronal loss and gliosis in the oculomotor (III), trochlear (IV), and abducens (VI) nuclei.
- These findings represent the first detailed neuropathological analysis of cranial nerve nuclei III, IV, and VI in an ALS patient with ophthalmoplegia.
Implications:
- This study highlights the potential for specific brainstem nuclei involvement in ALS.
- Understanding these neuropathological underpinnings may offer insights into the diverse clinical presentations of ALS and inform future research.
- Further investigation into the mechanisms causing ophthalmoplegia in ALS is warranted.

01:22Lysosomal Hydrolases
Lysosomes are the site for the degradation of macromolecules and biological polymers released during membrane trafficking events such as secretory, endocytic, autophagic, and phagocytic pathways. The membrane-enclosed area of the lysosome, called the lumen, contains hydrolytic enzymes active in an acidic environment. These acid hydrolases are functional at a pH between 4.5 and 5 and are involved in cellular processes such as cell signaling, energy metabolism, restoration of the plasma membrane,...
01:15Parkinson's Disease: Overview
Neurodegenerative disorders are progressive diseases that cause irreversible damage and loss to neurons in specific brain areas. Examples of these disorders include Parkinson's disease, Alzheimer's disease, Multiple Sclerosis (MS), and Amyotrophic Lateral Sclerosis (ALS). These disorders share characteristics such as proteinopathies, selective neuronal vulnerability, and a complex interplay between genetic and environmental factors. The primary therapeutic goal for these conditions is to...
01:19Multiple Sclerosis l: Introduction
Multiple sclerosis is a chronic autoimmune disease of the central nervous system (CNS) that affects the brain, spinal cord, and optic nerves. It is an inflammatory demyelinating disorder and a leading cause of neurological disability in young adults.EpidemiologyMS commonly begins between 20 and 40 years of age and is twice as common in women. Its exact cause remains unclear, but genetic susceptibility contributes, with higher risk in first-degree relatives and identical twins. A greater...
01:24Parkinson Disease ll: Pathophysiology
Parkinson disease (PD) is a progressive neurodegenerative disorder primarily affecting movement, with additional non-motor features. Its pathophysiology involves complex interactions among genetic susceptibility, environmental exposures, and cellular dysfunction, including dopaminergic neuron loss, protein aggregation, and mitochondrial impairment.Selective NeurodegenerationA key feature is the degeneration of dopaminergic neurons in the substantia nigra pars compacta, leading to reduced...
01:22Myasthenia 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...
01:11Alterations 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...
