Piaget's Stage 1 of Cognitive Development

Piaget's Stage 1 of Cognitive Development

The sensorimotor stage, the initial phase of Jean Piaget's theory of cognitive development, spans the first two years of a child's life. During this period, infants actively engage with their surroundings, building cognitive awareness through direct interaction with the world. This interaction is primarily based on sensory perception and motor actions, allowing infants to gradually understand basic physical properties and predict how objects interact within their environment.

Electroconvulsive Therapy

Electroconvulsive Therapy

Electroconvulsive therapy (ECT), or shock therapy, remains a critical biomedical intervention for severe, treatment-resistant depression. While its origins can be traced back to Hippocrates' observations that malaria-induced convulsions alleviated mental illness, modern ECT has evolved significantly from its earlier, more primitive applications. First introduced in 1938 by Ugo Cerletti and his colleagues, ECT involves inducing controlled seizures using electrical currents. In its early...

Emotional Expression

Emotional Expression

Emotional expression encompasses how individuals convey their emotions through verbal communication and non-verbal cues. These non-verbal actions include facial expressions, body language, and physical gestures, such as frowning or smiling. Among these, facial expressions play a crucial role in emotional expression and are understood universally, indicating a biological basis for how humans communicate emotions.

Summary

This summary is machine-generated.

Ictal crying is rare in epilepsy monitoring units, most often linked to psychogenic nonepileptic seizures (PNES). However, it can also occur in focal epilepsy, not specifically indicating PNES or localizing the seizure origin.

Area of Science:

Neurology
Epileptology
Clinical Neurophysiology

Background:

Ictal crying, or dacrystic seizures, is an uncommon ictal manifestation.
Understanding its occurrence and etiology is crucial for accurate diagnosis.

Purpose of the Study:

To describe patients experiencing ictal crying.
To estimate the frequency of ictal crying.
To characterize clinical features and underlying causes.

Main Methods:

Retrospective review of video-electroencephalogram (EEG) reports over 12 years.
Searched for terms related to crying, sobbing, or weeping.
Included patients with documented ictal crying episodes in the epilepsy monitoring unit (EMU).

Main Results:

Out of 5133 patients, 32 (0.6%) exhibited ictal crying.
Psychogenic nonepileptic seizures (PNES) were the most common cause (27 patients).
Five patients had epilepsy, including four with focal epilepsy and one with Lennox-Gastaut syndrome.

Conclusions:

Ictal crying is a rare finding in EMUs.
While often associated with PNES, it is not exclusive to it.
Epileptic ictal crying is typically a rare form of partial seizure in focal epilepsy and does not reliably predict seizure focus.
