Summary
Spasmus nutans, a common infant condition, often resolves but may persist. Many children recover well, though nystagmus, torticollis, and titubations can continue, necessitating ongoing monitoring.
Area of Science:
- Ophthalmology
- Neurology
- Pediatrics
Background:
- Spasmus nutans is an acquired nystagmus often seen in infancy.
- It is typically associated with head titubations and torticollis.
- Spasmus nutans is generally expected to resolve within two years.
Purpose of the Study:
- To evaluate the long-term prognosis of spasmus nutans in children.
- To characterize the persistence of symptoms and associated conditions.
Main Methods:
- A cohort of 22 patients under 21 years with spasmus nutans was studied.
- Data collected included age of onset, nystagmus characteristics, torticollis, titubations, strabismus, and neuroimaging findings.
- Follow-up duration averaged 62.6 months.
Main Results:
- Nystagmus persisted in 16 of 20 children, torticollis in 6 of 7, and titubations in 3 of 10.
- Neuroimaging was negative for space-occupying lesions in 17 patients.
- Average age of onset was 9.8 months.
Conclusions:
- Spasmus nutans prognosis is variable, and symptoms may persist beyond the typical resolution period.
- Normal neuroimaging is encouraging, but continued monitoring for nystagmus, torticollis, and strabismus is advised.
- Long-term follow-up is crucial for managing potential complications like amblyopia.

Long-term depression, or LTD, is one of the ways by which synaptic plasticity—changes in the strength of chemical synapses—can occur in the brain. LTD is the process of synaptic weakening that occurs over time between pre and postsynaptic neuronal connections. The synaptic weakening of LTD works in opposition to synaptic strengthening by long-term potentiation (LTP) and together are the main mechanisms that underlie learning and memory.

Regional terms describe anatomy by dividing the body parts into different regions that contain structures involved in contributing similar functions. Using these terms helps increase the accurate description and identification of the particular region of interest or region affected by the disease.
Primarily, the human body has two major regions, the axial and appendicular regions. The axial region comprises regions from the head to the abdomen and makes up the central body axis. In contrast,...

Long-term memory is a relatively permanent type of memory, capable of storing vast amounts of information over extended periods. Its storage capacity is generally considered unlimited.
Long-term memory can be categorized into two primary types: explicit and implicit memory. Explicit memory, also known as declarative memory, involves the conscious recollection of information that we deliberately try to remember, recall, and articulate. This type of memory encompasses specific facts, events, and...
