Q. 1

Dermatitis, diarrhoea and dementia are seen in deficiency of :

 A

Thiamine

 B

Riboflavin

 C

Niacin

 D

Methionine

Ans. C

Explanation:

The early symptoms of pellagra include loss of appetite, generalized weakness and irritability, abdominal pain, and vomiting.
Bright red glossitis then ensues, followed by a characteristic skin rash that is pigmented and scaling, particularly in skin areas exposed to sunlight.
This rash is known as Casal’s necklace because it forms a ring around the neck; it is seen in advanced cases.
Vaginitis and esophagitis also may occur. Diarrhea (in part due to proctitis and in part due to malabsorption), depression, seizures, and dementia are also part of the pellagra syndrome—the four Ds: dermatitis, diarrhea, and dementia leading to death.

  • Vascular dementia characteristically presents with – sudden onset in early age, stepwise & patchy progression with focal neurological signs & symptomsQ & greater preservation of personality.

  • FTD often begins in the 5′hto 7th decades.
  • Patients with FTD often show an absence of insight into their condition.
  • Common behavioral features include apathy, disinhibition, weight gain, food fetishes, compulsions, and emotional distance or loss of empathy.
Fronto-Temporal Dementia

FTD often begins in the 5′ to 7′ decades’)

More common in menu

Unlike in Alzheimer’s disease (AD), behavioral symptoms predominate in the early stages of FTD°

Family history of dementia is common° 

MC autosomal dominantly inherited mutations causing FTD involve the MAPT or GRN genes, both on chromosome 17.

Clinical features:

Early symptoms are divided among behavioral, language, and sometimes motor abnormalities, reflecting degeneration of the anterior insular, frontal, and temporal regions, basal ganglia, and motor neurons.

Cognitive testing typically reveals spared memory but impaired planning, judgment, or language°.

Poor business decisions and difficulty organizing work tasks are common, and speech and language deficits often emerge.

Patients with FTD often show an absence of insight into their condition.

Common behavioral features include apathy, disinhibition, weight gain, food fetishes, compulsions, and emotional distance or loss of empathy.

Diagnosis:

Distinguishing anatomic hallmark of FTD: Focal atrophy of frontal, insular, and/or temporal cortex, which can be visualized with neuroimaging studies (MRI)° 

Microscopic findings seen across all patients with FTD include gliosis, microvacuolation, and neuronal loss°
