Summary
Mirror writing, a rare neurological symptom, emerged in a patient after subarachnoid hemorrhage. This unusual writing phenomenon resolved spontaneously within two months, offering new insights into post-hemorrhage neurological recovery.
Area of Science:
- Neuroscience
- Neurology
- Clinical Case Reports
Background:
- Mirror writing is a rare neurological phenomenon where individuals write text in a reversed manner, often from right to left.
- Subarachnoid hemorrhage (SAH) can lead to various neurological deficits, but mirror writing is an infrequently reported consequence.
- Perimesencephalic SAH is a specific subtype of SAH characterized by bleeding around the midbrain, typically with a good prognosis.
Observation:
- A right-handed Caucasian woman developed mirror writing after a non-aneurysmal, non-traumatic subarachnoid hemorrhage.
- The patient was initially unaware of the mirror writing, which was noticed by clinical staff.
- Serial neuroimaging excluded stroke and vascular abnormalities as causes.
Findings:
- This case represents the first documented instance of mirror writing associated with perimesencephalic subarachnoid hemorrhage.
- The phenomenon resolved spontaneously over a two-month period without specific intervention.
Implications:
- This case expands the known spectrum of neurological manifestations following subarachnoid hemorrhage.
- It highlights the importance of careful clinical observation for subtle neurological signs.
- Further research may elucidate the specific pathophysiological mechanisms linking perimesencephalic SAH to transient mirror writing.

01:11Guidelines for Writing Outcome
3.7K
When developing expected outcomes for a patient care plan, the nurse should adhere to the following recommendations:
Patient outcomes reflect the patient's response to the goal rather than what the nurse aims to achieve. Terminology should be observable and measurable to avoid the reader's interpretation. The desired outcome should be realistic and achievable in the designated care timeframe. Expected outcomes should align with adjunctive therapies. The outcome should enhance care...

03:26Electron Configuration of Multielectron Atoms
64.7K
The alkali metal sodium (atomic number 11) has one more electron than the neon atom. This electron must go into the lowest-energy subshell available, the 3s orbital, giving a 1s22s22p63s1 configuration. The electrons occupying the outermost shell orbital(s) (highest value of n) are called valence electrons, and those occupying the inner shell orbitals are called core electrons. Since the core electron shells correspond to noble gas electron configurations, we can abbreviate electron...

02:10Social Scripts
10.3K
People tend to know what behavior is expected of them in specific, familiar settings. A script is a person’s knowledge about the sequence of events expected in a specific setting (Schank & Abelson, 1977). Essentially, scripts are a particular kind of schema, one containing default values for the features within an event. In the restaurant example, the script's features include the props (e.g., tables, menu, food, and money), the roles to be played (e.g., customer and waiter),...

Social psychologists have documented that feeling good about ourselves and maintaining positive self-esteem is a powerful motivator of human behavior (Tavris & Aronson, 2008). In the United States, members of the predominant culture typically think very highly of themselves and view themselves as good people who are above average on many desirable traits (Ehrlinger, Gilovich, & Ross, 2005). Often, our behavior, attitudes, and beliefs are affected when we experience a threat to our...

02:25Spreading of Chromatin Modifications
9.4K
The histone proteins in the nucleosomes are post-translationally modified (PTM) to increase or decrease access to DNA. The commonly observed PTMs are methylation, acetylation, phosphorylation, and ubiquitination of lysine amino acids in the histone H3 tail region. These histone modifications have specific meaning for the cell. Hence, they are called "histone code". The protein complex involved in histone modification is termed as "reader-writer" complex.
