severe depression)
![Page 24: Psychosis Due to Endocrine DISTURBANCES](https://reader036.vdocuments.us/reader036/viewer/2022081413/546a7e10b4af9f38018b4717/html5/thumbnails/24.jpg)

concentration and memory)
![Page 25: Psychosis Due to Endocrine DISTURBANCES](https://reader036.vdocuments.us/reader036/viewer/2022081413/546a7e10b4af9f38018b4717/html5/thumbnails/25.jpg)
Differences of Cushing’s syndrome from Major depressive disorder
1)greater irritability and mood lability2)greater tendency to feel best in the
morning3)less guilt and hopelessness
compared to patients with major depression
![Page 26: Psychosis Due to Endocrine DISTURBANCES](https://reader036.vdocuments.us/reader036/viewer/2022081413/546a7e10b4af9f38018b4717/html5/thumbnails/26.jpg)
Treatment and Course• Treatment of pituitary ACTH-producing tumors surgical resection pituitary irradiation
• Adrenal adenomas and carcinomas removed surgically chemotherapy is instituted in case of carcinoma
• Medications that antagonize cortisol production metyrapone or mitotane [tysobren]
• Medications that suppress ACTH serotonin antagonists (eg. cyproheptadine [Periactin])
• Prednisone treatment, lithium and neuroleptic medications
help prevent the development of manic or psychotic symptoms
![Page 27: Psychosis Due to Endocrine DISTURBANCES](https://reader036.vdocuments.us/reader036/viewer/2022081413/546a7e10b4af9f38018b4717/html5/thumbnails/27.jpg)
Adrenocortical Insufficiency
inadequate production of three major steroid hormones
Primary adrenal insufficiency adrenal hypofunction
Secondary adrenal insufficiency results from deficient ACTH secretion
Tertiary adrenal insufficiency refers to deficient hypothalamic secretion of CRH
![Page 28: Psychosis Due to Endocrine DISTURBANCES](https://reader036.vdocuments.us/reader036/viewer/2022081413/546a7e10b4af9f38018b4717/html5/thumbnails/28.jpg)
Symptoms of adrenal insufficiency include weakness, hypoglycemia, hyponatremia,
hyperkalemia, nausea, diarrhea, fever, symptoms, including fatigability, salt craving, weight loss, vitiligo, nausea, hyperpigmetntation, loss of ACTH stimulation test
symptoms of chronic adrenal insufficiency overlap those of depression
![Page 29: Psychosis Due to Endocrine DISTURBANCES](https://reader036.vdocuments.us/reader036/viewer/2022081413/546a7e10b4af9f38018b4717/html5/thumbnails/29.jpg)
Pathology and Laboratory Examination
Laboratory findings: low serum concentrations of sodium high concentrations of potassium low or normal plasma cortisol concentrations
![Page 30: Psychosis Due to Endocrine DISTURBANCES](https://reader036.vdocuments.us/reader036/viewer/2022081413/546a7e10b4af9f38018b4717/html5/thumbnails/30.jpg)
Treatment Acute adrenal insufficiency requires immediate treatment with intravenous
hydrocortisone in addition to fluid replacement with saline solution and potassium supplementation
Primary adrenal insufficiency Mineralocorticoid
e.g., fludrocortisone [Florinef]
Chronic adrenal insufficiency prednisone or hydrocortisone is administered
orally as maintenance treat
![Page 31: Psychosis Due to Endocrine DISTURBANCES](https://reader036.vdocuments.us/reader036/viewer/2022081413/546a7e10b4af9f38018b4717/html5/thumbnails/31.jpg)

regulates the serum calcium through its effect on the bones, gut and the kidney.
Dysfunction of parathyroid gland leads to abnormal regulation of the calcium metabolism.
Hypercalcemia results to: delirium personality changes apathy cognitive impairments
![Page 33: Psychosis Due to Endocrine DISTURBANCES](https://reader036.vdocuments.us/reader036/viewer/2022081413/546a7e10b4af9f38018b4717/html5/thumbnails/33.jpg)
Hypocalcemia
personality changes and delirium
psychiatric symptoms without the characteristic tetany of hypocalcemia is observed if calcium gradually decreases.
