U.S. NeuroStar Advanced Therapy System revenue increased by $6.8 million, or 70%, in the year ended December 31, 2022 compared to the year ended December 31, 2021. For the period ended December 31, 2022 and 2021, the Company shipped 213 and 147 systems, respectively.
U.S. treatment session revenues increased by 7% from $41.9 million for the year end December 31, 2021 to $45.1 million for the year ended December 31, 2022. The revenue growth was primarily driven by an increase in treatment session volume over the prior year period.
Gross margin for the full year 2022 was 76.3%, a decrease of approximately 260 basis points from the full year 2021 gross margin of 78.9%. The decline was primarily due to an unfavorable revenue shift between NeuroStar capital and treatment session revenue.
Operating expenses during the full year 2022 were $84.8 million, an increase of $13.6 million, or 19.1%, compared to $71.2 million in the full year 2021. The increase was primarily driven by higher sales and marketing expense related to personnel, new marketing initiatives and opening of NeuroStar University. Our Research and Development costs were also higher in 2022, as the company invested in added personnel to support clinical research projects and continued upgrades to the NeuroStar Advanced Therapy system. Inflationary pressures resulted in higher travel expense.
Net loss for the full year 2022 was $(37.2) million, or $(1.38) per share, as compared to full year 2021 net loss of $(31.2) million, or $(1.22) per share. Net loss per share was based on 26,900,239 and 25,479,425 weighted-average common shares outstanding for the years ended 2022 and 2021, respectively. There were 27,267,867 shares outstanding as of December 31, 2022.
EBITDA for the full year 2022 was $(31.3) million as compared to $(26.1) million for the full year 2021. The decrease in EBITDA is primarily due to the increase in net loss in the current period compared to the comparative prior period. See the accompanying financial table that reconciles EBITDA, which is a non-GAAP financial measure, to net loss.
Cash and cash equivalents were $70.3 million as of December 31, 2022. This compares to cash and cash equivalents of $94.1 million as of December 31, 2021.
