Which of the following best describes dyscalculia?
Difficulty in reading skills.
Difficulty in fine motor skills.
Difficulty in math skills.
Difficulty in writing.
The Correct Answer is C
A. Difficulty in reading skills. This describes dyslexia, a learning disorder characterized by challenges in reading, spelling, and phonemic awareness. Individuals with dyslexia may struggle with word recognition, reading fluency, and comprehension, but their math skills may remain unaffected.
B. Difficulty in fine motor skills. This describes dyspraxia (developmental coordination disorder), which affects motor planning and coordination rather than numerical skills. Individuals with dyspraxia may struggle with writing, buttoning clothes, or other tasks requiring precise hand movements.
C. Difficulty in math skills. Dyscalculia is a specific learning disability in mathematics, affecting number sense, calculations, problem-solving, and understanding mathematical concepts. It is linked to difficulties in basic arithmetic, number sequencing, and spatial reasoning, often unrelated to intelligence or overall cognitive ability.
D. Difficulty in writing. This describes dysgraphia, a learning disorder that impairs handwriting, spelling, and written expression. Individuals with dysgraphia may have poor letter formation, inconsistent spacing, and difficulty organizing thoughts on paper, but their math abilities may not be affected.

A. Cesar's Assessment Scale. There is no widely recognized Cesar's Assessment Scale for diagnosing ADHD.
B. Hamilton Assessment Scale. The Hamilton scales (HAM-A and HAM-D) are used to assess anxiety and depression, not ADHD. They measure emotional symptoms, somatic complaints, and cognitive impairments associated with mood disorders.
C. Vanderbilt Assessment Scale. The Vanderbilt Assessment Scale is a validated tool used for ADHD diagnosis in children. It assesses inattention, hyperactivity, impulsivity, and associated behavioral problems based on parent and teacher reports. It also screens for common comorbidities such as oppositional defiant disorder (ODD) and anxiety disorders.
D. Columbia Assessment Scale. The Columbia Suicide Severity Rating Scale (C-SSRS) is used to assess suicidal ideation and behavior, not ADHD. It is primarily applied in psychiatric evaluations and crisis intervention settings.
Correct Answer is D
Explanation
A. Clozapine (Clozaril) is a second-generation (atypical) antipsychotic with a high risk of weight gain, metabolic syndrome, and sedation due to its strong antagonism of histamine (H1) and serotonin (5-HT2C) receptors. It can also cause sexual dysfunction due to its impact on dopamine and prolactin levels.
B. Olanzapine (Zyprexa) has a significant risk of weight gain and metabolic side effects, similar to clozapine. It is known to cause hyperlipidemia, insulin resistance, and increased appetite, contributing to obesity. Sexual dysfunction can occur but is less common than with prolactin-elevating antipsychotics.
C. Haloperidol (Haldol) is a first-generation (typical) antipsychotic with a high risk of sexual dysfunction due to prolactin elevation from strong dopamine (D2) receptor blockade. While it has a lower risk of weight gain than atypical antipsychotics, it carries a high risk of extrapyramidal symptoms (EPS).
D. Aripiprazole (Abilify) is a partial dopamine agonist and has the lowest risk of weight gain among atypical antipsychotics. It also has a minimal impact on prolactin levels, reducing the risk of sexual dysfunction. Due to its unique mechanism, it is often preferred for patients concerned about metabolic side effects and sexual health.
